Abstract ：
At present, the global tunnel construction industry is developing rapidly, but construction accidents are also common. A large number of casualties and property losses are alarming people. It is urgent to pay attention to the causes of tunnel construction accidents, ensure the safety of construction sites, and reduce tunnel construction accidents. Through literature and case analysis, we have sorted out 35 typical tunnel causative factors for research and analysis, which are divided into 7 types. Based on the variable system, we prepared a measurement questionnaire, and 536 valid questionnaires were collected. The structural equation model (SEM) was used to study the relationship between these variables. The influence mechanism and interaction relationship between the variables are analyzed in depth in terms of influence intensity and path coefficient. The results showed that the following six latent variables significantly influence tunnel construction accidents: human factors, material factors, geological exploration design, technical management, safety management, and natural conditions. Natural conditions have the most significant impact, followed by human factors and safety management. Particular attention should be paid to education, training, and safety management in construction risk control. The structural model and research results are helpful to establish the cause theory of tunnel construction accidents, and guide the formulation of safety management policies for tunnel construction projects, reduce tunnel accidents and ensure construction safety.

Abstract ：
Despite the continuous progress of tunnel construction technology and safety management technology, road tunnel construction safety still faces many challenges in China, such as how to ensure the effective management and safety control of people and materials, how to ensure the implementation of technology and program implementation, risk assessment of construction site environmental information, etc. Exploring the causes of tunnel construction accidents and understanding the properties of the factors and their interrelationships can effectively control the sources of risk and contribute to the safety control of tunnel construction. Therefore, we have collected 30 formal accident investigation reports from the government safety supervision and management department from 2005 to 2021, including detailed investigation and accident analysis. Based on grounded theory, a qualitative research method to generalize experience through direct observation, abstraction, and analysis of data, we use Nvivo11 software to analyze reports and obtain 6 selective codes, 16 spindle codes, and 43 open codes. In addition, we construct a theoretical model of tunnel construction accident influencing factors, which passed the saturation test. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) model is used to analyze the influencing mechanism and interaction relationships of these factors. The two dimensions of influence degree and centrality are used to determine the critical influencing factors of tunnel construction accidents in mountainous areas. They are security awareness and professionalism. According to the cause degree, the influencing factors are divided into cause and result factors. Finally, the basis and suggestions for reducing construction accidents are presented.

Abstract ：
针对中空注浆锚杆动力检测问题,分别基于现场试验和数值模拟,从固结波速和衰减系数2个方向,探讨了水泥浆龄期对中空注浆锚杆动力检测效果的影响.研究表明,在不同水泥浆龄期作用下,锚固体系的固结波速和衰减系数均有一个先减小后增大的趋势;在锚杆砂浆密实情况下,中空注浆锚杆的衰减系数在0.34～0.42.在初凝(45min)时最小,在7d龄期时最大,其数值相差较大,建议注浆7d后再对中空注浆锚杆分别检测.

Abstract ：
本文基于ANSYS有限元软件模拟了混凝土偏心受压构件工作应力的开槽法释放过程。通过外加荷载应力场模拟现存应力,用应力释放深度描述释放规律,用生死单元技术模拟开槽过程,研究了方型环孔、开槽间距和应力初值等因素对弹性应力释放规律的影响。结果表明:应力释放值依赖于开槽形式、开槽间距和应力初值;采用方形环孔和开横槽的测试形式对完全释放深度无影响;完全释放深度随开槽间距的增大而增大,但与应力初值无关。

Abstract ：
When tunnel passes through fracture zone in an orthogonal manner, the embedded depth plays a crucial role in seismic response of tunnel. This article, by numerical simulation, respectively calculates the speed and acceleration as well as the scope of plastic zone on key points of tunnel lining structure and also makes the comparison when the embedded depth is respectively 2D, 5D and 8D and when the surrounding rock grade is Grade IV and the width of fault fracture zone is 10 m. The study shows that, when the embedded depth is 8D, the dynamic response of tunnel is respectively smaller, and the influence of fault fracture zone is less; when the embedded depth is 2D, the dynamic response of tunnels through fault fracture zone is significantly greater than that without fault fracture zone, and the lining structure is dominated by shear fracture. © 2016 Taylor & Francis Group, London.

Abstract ：
以福建南平狮子山隧道为依托，通过MIDAS／GTS有限元程序对不同二衬厚度情况下后行隧道爆破时先行隧道二衬的振速及衬砌应力进行了数值模拟。结果表明，迎爆侧拱腰处其X方向，即水平并垂直隧道轴线方向振速最大；随着二衬厚度的增加，最大振速在一定程度上逐渐减小，二衬X方向上的最大应力却基本不变。
