Abstract ：
Accurate prediction of shield machine position and attitude is crucial for ensuring the quality of tunnel construction. However, current machine learning models for predicting the position and attitude deviations of shield machines encounter significant challenges in achieving reliable long-term forecasting during shield tunneling. This study introduces a novel deep learning model, termed 1DCNN-Informer, which integrates the onedimensional convolutional neural network (1DCNN) and the Informer model. The model was trained and validated using datasets from the Nanjing Metro shield tunnel project in China. Furthermore, the 1DCNN-Informer model was transferred to datasets from both similar and different geological conditions using the domain adversarial neural network (DANN) transfer learning method. The importance of input features was analyzed using the Shapley additive explanations (SHAP) method, complemented by experiments with various input parameter combinations. Results demonstrate that the 1DCNN-Informer model achieves superior performance compared to the Informer model and surpasses other comparative models, such as PatchTST, iTransformer, and Dlinear, in the majority of input sequence length and prediction sequence length combinations. Additionally, the DANN transfer learning method significantly enhances the 1DCNN-Informer model's performance in the target domains dataset. The cutterhead rotation speed, advance speed, and chamber pressure are of critical importance in the prediction of shield position and attitude deviation. The proposed model not only represents a significant advancement in intelligent shield tunneling but also holds potential for broader application in automated equipment operations and multi-domain transfer learning studies in the field of engineering.

Abstract ：
In tunnelling using tunnel boring machine (TBM), the surrounding rocks are typically supported by precast lining segments, pea-gravel backfilling and grouting. The compactness of the backfill layer is critical for ensuring the safety of the tunnel construction. However, poor fluidity of cement generally leads to uneven grouting effects, resulting in lower density in certain areas of the backfill layer. In contrast, enzyme-induced carbonate precipitation (EICP) is an environmentally friendly and sustainable technique which has superior mobility and diffusivity compared to cement. To investigate the reinforcement effects of EICP technique on backfill layer, a series of bio-cemented sand column tests and model tests were conducted in this study. The optimal working range of pea gravel and sand for effective bio-cementation were determined by comparing the permeability, unconfined compressive strength (UCS), calcium carbonate content (CCC), and wave velocity of bio-cemented sand columns. The effects and homogeneity of reinforcement based on model tests were assessed by point load tests, wave velocity measurements, and calcium carbonate content evaluations. The model tests with different grouting hole layout density were conducted to obtain the optimal hole placement scheme. The column test results demonstrated that the optimal working range of pea gravel to sand ratio for effective bio-cementation is 1.25-1.5. As the number of grouting cycles increases, the point load strength, wave velocity, CCC and UCS of the specimens increase while the permeability of the specimens decreases. The point load strength of bio-cemented specimens could reach up to 16.53 MPa, while the permeability was reduced by three orders of magnitude compared with that of untreated specimens. The EICP has been demonstrated to be an effective technique capable of improving the compactness and strength of the backfill layer, with aggregates effectively cemented by calcium carbonate generated. The model test results demonstrated that the full-coverage arrangement hole scheme achieves uniform cementation, while the space arrangement hole scheme produces concentrated CaCO3 near grouting holes. Furthermore, a new and improved grouting scheme is proposed based on the model test results. The data obtained in this study offer valuable references for the reinforcement of the backfill layer in TBM tunnelling using the EICP technology.

Abstract ：
A rigorous mathematical model is developed to analyze the kinematic response of monopiles embedded in the seabed under vertically incident P-waves. The seabed is considered to consist of nearly saturated soil, in which the mixture of pore water and dissolved air bubbles is treated as a homogeneous fluid phase. The governing equations of soil and pile are formulated using the Biot's poroelastodynamic theory and one-dimensional bar vibration theory, respectively. The frictional forces between the inner and outer soil layers are derived, and a closed-form series solution for the monopile's vertical seismic response is obtained by applying the boundary conditions of the pile-soil system. The proposed solution is validated through comparisons with existing studies and is subsequently used to explore the effects of key parameters and the role of inner soil on the seismic behavior of the soil-pile system, leading to several significant conclusions.

Abstract ：
Soil conditioning of gravel-clay strata using foams for earth pressure balance (EPB) shield tunnelling is less well understood compared to conditioning for clay or sand strata. This lack of understanding can lead to muck clogging at the cutting wheel and increased wear on cutter tools. To address these issues, this study introduces the response surface methodology (RSM) to investigate the effects of various foaming agent components and their interactions on foam conditioning of gravel-clay strata that are widely distributed in Southeastern China. The controlled variables selected for this study include anionic surfactant sodium fatty alcohol polyoxyethylene ether sulfate, nonionic surfactant alkyl polyglycoside, foam stabilizer hollyhock gum, organic dispersant guar gum, and inorganic dispersant sodium tripolyphosphate. The responses evaluated are the foaming agent viscosity, foam volume, foam half-life time, adhesive force, and undrained shear strength. Fifty groups of laboratory tests, including apparent viscosity, Ross-Miles, liquid loss, improved cone pull-out, and vane shear tests, are conducted to characterize these responses. The surface tension measurements and microscopic observations are also performed to interpret foam performance. Ultimately, the optimal ratio of foaming agent components is determined using the desirability approach. The comparison of in-house and commercial foaming agents in both laboratory and in-situ tests, focusing on their conditioning effects on soil properties and tunnelling parameters, highlights the applicability of the proposed RSM models. This study offers new insight into the consequence and interaction of different foaming agent components and serves as a valuable reference for soil conditioning of gravel-clay strata during EPB shield tunnelling.

Abstract ：
Hydraulic fill sand strata in coastal areas were prone to differential settlements under the self-consolidation to form undulating ground surfaces.Shallow tunnel faces were often in passive failure modes when shield tunneling in hydraulic fill sand strata. However, traditional tunnel face stability analysis models lacked a comprehensive consideration of above two factors. More accurate passive failure analysis models of tunnel face under undulating ground surfaces urgent need to be explored.The influence exerted by longitudinal slope δ1 and transverse slope δ2 on the ultimate support pressures and the failure zone was investigated by numerical simulations. According to the failure zone obtained from numerical simulations, a 3D passive failure model was proposed by using the spatial discretization technique, and ultimate support pressure upper-bound solutions were derived based on limit analysis methods. The results demonstrated that the influence of bidirectional slopes cannot be ignored in practical engineering, the longitudinal slope δ1 has a more significant impact on the ultimate support pressure than the transverse slope δ2, the effect of transverse slope δ2 on the extent of the failure zone was more important than that of longitudinal slope δ1.Finally, validated by comparison with numerical models and existing analytical models and with a case study.The proposed results were closer to numerical results.The results can provide theoretical guidance for shield tunneling under complex terrain conditions. © 2025 Editorial Board of Journal of Basic Science and Engineering.

Abstract ：
Microbial-induced carbonate precipitation (MICP) technique has the potential to be an eco-friendly and sustainable solution for engineering problems. Despite the extensive amount of research that has been conducted recently on the MICP technique, there are few studies on the constitutive model of MICP-treated specimens. In this study, the statistical damage constitutive model of MICP-treated specimens was established based on the statistical theory and damage mechanics theory. The proposed model assumed that the microelement strength of biocemented sand follows the lognormal distribution and the Drucker-Prager criterion. The parameters S0 and F0 in the constitutive model were determined, and their physical significance was then discussed. The reasonableness of the proposed model was verified by comparing the theoretical results and the experimental results. The evolution of the damage variable (D), parameter S0, and parameter F0 with different calcium carbonate content (CCC) was analyzed. The statistical damage model based on the lognormal distribution was then compared with that based on the Weibull distribution. The results show that the parameter F0 and S0 can reflect the limiting strength and brittleness of MICP-treated specimens.. The specimens with higher cementation tend to have a higher accelerated damage rate. The damage variables eventually reach a stable value as the axial deformation increases. The proposed model can reflect the strain softening and strain hardening phenomena well, which can also represent the shear expansion and shear contraction characteristics of the volume strain curve. Overall, the research in this study can provide some theoretical support for the engineering application of MICP-treated specimens.

Abstract ：
Land reclamation from the sea is increasingly common in coastal areas in China as its urban population continues to grow and the construction of subways in these areas becomes an effective way to alleviate transportation problems. Earth pressure balance shield (EPBS) tunneling in reclaimed lands often faces the problem of seawater erosion which can significantly affect the effectiveness of soil conditioning. To investigate the impacts, in this work, the stratum adaptability of EPBS foaming agents in seawater environments was evaluated based on a series of laboratory tests. The Atterberg limits and vane shear tests were carried out to understand the evolution characteristics of mechanical properties of clay-rich soils soaked in seawater and then conditioned with foams. The results revealed that, for the same foaming agents, the liquid limit and plastic limit of soils soaked in seawater were lower than those in deionized water due to the thinning of bound water films adsorbed on the surface of soil particles. Similarly, soils soaked in seawater had lower shear strength. In addition, the results indicated that the foam volume (FV) produced by foaming agents using seawater as the solvent was slightly higher than that when using the deionized water due to the higher hydration capacity of inorganic salt cations in seawater compared with organic substances. It was also shown that seawater had negative effects on the half-life time (T1/2) and the dynamic viscosity (eta) of foaming agents due to the neutralization reaction between anions in the foaming agents and Na+ present in seawater. The test results also confirmed that 0.5 % of the tackifier (CMC) can alleviate the issue of thin foam films caused by seawater intrusion and improve the dynamic viscosity of foaming agents more effectively, leading to superior resistance to seawater intrusion in EPBS tunnel constructions.

Abstract ：
Shear-induced rock bridge fractures greatly threaten the stability of rock slopes and deep rock masses, owing to their connection with pre-existing discontinuities. In this research, direct shear tests on sandstone rock bridges were performed under constant normal stiffness (CNS) conditions. The effects of rock bridge length, initial normal stress and normal stiffness on the shear behavior of rock bridges were carefully investigated, encompassing both the pre-failure (cracking phase) and post-failure (sliding phase) stages. Test results revealed that these three factors variably impact the shear strength, dilation characteristics, failure pattern and acoustic emission response of the rock bridges. In particular, normal stiffness was found to greatly affect the post-peak slip behavior. It was observed that shear-induced rock bridge fractures exhibit distinctive shear contraction characteristics, which contrast with tension-induced splitting fractures that are typically marked by shear dilation. The shear contraction mechanism of rock bridge fractures was elucidated using a conceptual cracking model, termed the TST model. This research contributes fresh insights to the comprehension of dynamic slip hazards prompted by the rupture of rock bridges in deep rock engineering.

海域吹填砂地层在自重固结作用下易产生差异沉降形成起伏地表,浅埋盾构隧道在该类地层掘进时开挖面常处于被动土压模式,传统开挖面稳定性理论分析模型欠缺对以上两类影响因素的综合考虑,亟需探索针对起伏地表情况下更为精确的开挖面被动破坏分析模型.通过数值模拟研究了地表纵向坡度δ1和横向坡度δ2对极限支护压力和破坏区的影响,并根据数值模拟得到破坏区的范围.然后采用空间离散化技术,提出一种三维被动破坏模型,通过极限分析法推导了极限支护压力的上限解.分析结果表明:在实际工程中起伏地表双向坡度的影响不可忽略,地表纵向坡度δ1比横向坡度δ2对极限支护压力的影响更为明显;横向坡度δ2对破坏区范围的影响比纵向坡度δ1更为显著.最后,通过与数值模型和现有方法比较并结合工程实例验证,发现所提出的理论模型与数值模型模拟的结果更为接近.上述研究成果可为复杂地形下盾构法施工提供理论指导.
