Abstract ：
Recent advances have significantly enhanced dynamic early warning systems for rainfall-induced landslides by integrating rainfall thresholds with susceptibility mapping. However, there is still room for optimizing these models for regional-scale applications. This study introduces a dynamic early warning model in Anxi County, Fujian Province, China-a region prone to rainfall-induced landslides. First, historical landslide data and their controlling factors were analyzed for the study area, and an optimal landslide susceptibility map was produced by integrating an information value model with a logistic regression model. Second, based on the theory of effective rainfall, the regional rainfall threshold model was established according to the indices of daily and hourly rainfall, and the model's accuracy was evaluated. Third, the more effective E-D (daily index) and EE-D (hourly index) models were coupled with the landslide susceptibility map for landslide dynamic early warning. The model's validation results show its significant predictive capabilities, with the hourly model proving more accurate for short-duration rainfall events. This study provides valuable insights for local authorities on dynamic early warning for rainfall-induced landslides and offers guidance for refining dynamic early warning systems in similar regions.

Abstract ：
As large-scale photovoltaic power plants gradually move towards high-altitude and cold regions, accurate evaluation of the impact of freeze-thaw erosion hazards on the safe operation of photovoltaic power plants is essential. This study, based on a large-scale photovoltaic power plant in a high-altitude and cold area, conducted an initial calculation of the freeze-thaw erosion intensity in the study area by selecting appropriate environmental factors. By coupling human engineering quantitative indicators, a targeted and reasonable evaluation model for the freeze-thaw erosion intensity of photovoltaic sites was proposed, and the freeze-thaw erosion intensity and its spatial distribution under multiple environmental factors and human engineering conditions were explored. The results showed that the freeze-thaw erosion intensity of the photovoltaic site was generally moderate, with a certain degree of concentration and spatial heterogeneity in its distribution, which was mainly affected by topography, climate, and vegetation factors. Furthermore, the construction of the photovoltaic power plant had a certain weakening effect on the freeze-thaw erosion intensity of the site. The research results can provide reference and guidance for the freeze-thaw erosion evaluation of similar large-scale projects. © 2024 Institute of Engineering Mechanics (IEM). All rights reserved.

Abstract ：
Background Extreme wildfires pose a serious threat to forest vegetation and human life because they spread more rapidly and are more intense than conventional wildfires. Detecting extreme wildfires is challenging due to their visual similarities to traditional fires, and existing models primarily detect the presence or absence of fires without focusing on distinguishing extreme wildfires and providing warnings.Aims To test a system for real time detection of four extreme wildfires.Methods We proposed a novel lightweight model, called LEF-YOLO, based on the YOLOv5 framework. To make the model lightweight, we introduce the bottleneck structure of MobileNetv3 and use depthwise separable convolution instead of conventional convolution. To improve the model's detection accuracy, we apply a multiscale feature fusion strategy and use a Coordinate Attention and Spatial Pyramid Pooling-Fast block to enhance feature extraction.Key results The LEF-YOLO model outperformed the comparison model on the extreme wildfire dataset we constructed, with our model having excellent performance of 2.7 GFLOPs, 61 FPS and 87.9% mAP.Conclusions The detection speed and accuracy of LEF-YOLO can be utilised for the real-time detection of four extreme wildfires in forest fire scenes.Implications The system can facilitate fire control decision-making and foster the intersection between fire science and computer science. We tested a lightweight architecture called LEF-YOLO for detecting four extreme wildfires. We found improved detection accuracy through multi-scale fusion and attention mechanism, and constructed four extreme wildfire datasets and compared these with multiple object detection models and lightweight feature extraction networks. This method is beneficial for the development of extreme wildfire field robots.

Abstract ：
[目的]揭示动水头作用下花岗岩风化土侵蚀演化的动态过程，研究动态水力条件对土体内部侵蚀发展的影响，探明颗粒迁移规律与内部侵蚀机理，为深入研究花岗岩边坡的破坏模式与促滑机理提供理论依据。[方法]设计竖向土柱渗流装置，开展上升水头与正弦水头条件下花岗岩风化土柱的渗流试验，基于渗流土柱顶面与侧面的试验现象，从渗流速度变化、颗粒流失量变化和渗流前后颗粒级配、质量变化等方面，分析动水头作用下花岗岩风化土内部侵蚀的发育特征。[结果](1)花岗岩风化土粒径差异较大，在骨架间存在微小孔隙，渗流冲刷作用使得土颗粒通过土体骨架间的孔隙运移流失。在内部侵蚀过程中，细颗粒流失量相对较多，粗颗粒流失量较少。(2)土体内部侵蚀作用是渐进发展的过程，在土体薄弱区域的结构最先产生变形与破坏。试验中渗流泉眼由土柱边界开始发展到土柱中部区域，渗流通道沿着渗流方向自下而上发育，水力条件短时间内发生显著变化会造成渗流通道快速贯通。(3)土体内部侵蚀作用将随渗流时间推进而趋于稳定，但正弦水头将“激活”土颗粒运动，加剧土体的内部侵蚀作用。加大水头变化幅度或减小水头变化周期，能够加剧土体内部侵蚀作用，导致水流运移速度加快以及颗粒迁移流失量增多。[结论]水力条件变化对土体内部侵蚀作用存在显著影响，正弦水头更能加剧颗粒迁移流失。

Abstract ：
The upper bound theorem (UBT) is widely used in the stability analysis of geosynthetic-reinforced slopes (GRSs). However, the existing research seldom considers multiple potential failure mechanisms when using the UBT to design GRSs. First, based on the upper bound theorem of limit analysis, considering multiple failure modes of GRSs, a translation slicing mechanism was constructed. The implicit equation aiming at the safety factor of GRSs was derived, and a simple and effective discrete iteration method was proposed. Second, the rationality of the method proposed in the paper was verified by comparing the existing examples and calculation methods of GRSs. The results showed that the method can consider multiple potential failure modes of GRSs and accurately determine the critical slip surface and minimum safety factor. Finally, the method examined the influences of soil mechanical parameters, reinforcement distribution patterns, and geosynthetic-reinforcement parameters on the critical failure mechanisms and corresponding minimum safety factors. The results showed that when the multiple potential failure mechanisms of GRSs are fully considered, the critical slip surface may not only be sheared from the slope toe for different distribution patterns. It further showed that it is necessary to consider multiple potential failure mechanisms in the design of GRSs. The interval of external critical failure of GRSs increased with the increase of soil cohesion and decreased with the increase of slope angle and internal friction angle. The interval of the internal critical failure of GRSs increased with the increase of slope angle and internal friction angle. The research results provide a novel idea and theoretical support for the stability calculation of GRSs.

闽东南高植被覆盖区台风暴雨型滑坡频发，探索在植被、降雨、强风作用下的滑坡失稳演化及其规律对揭示高植被覆盖区台风暴雨型滑坡的成灾机制、监测预警具有重要的理论及实际意义。以福建省永泰县洋斜滑坡为研究对象，对斜坡上的毛竹进行拉拔试验以及对根土区进行单环入渗试验，结合Green-Ampt模型和无限边坡模型，研究在台风暴雨作用下植被土坡的稳定性响应规律及其稳定性分析方法。结果表明：（1）毛竹抵御的极限风速主要在18～30 m/s的范围之内，对应8～11级风力范围。（2）毛竹迎风区土体入渗能力随着风速的增长而增长，0～12 m/s内入渗能力基本不变，12 m/s以上入渗能力迅速增长。（3）根土区湿润锋的迁移速度随着风速和降雨强度的增大而加快，台风通过植被扰动土体形成优势渗流，对入渗的影响主要在于加快了湿润锋的迁移速度。风-雨-植被协同作用下，风速是影响土体入渗能力的重要因素。（4）台风暴雨作用下风荷载通过植被加快根区土降雨入渗，从而增大湿润锋迁移速度，是台风暴雨型滑坡孕灾、成灾的重要环节。

Abstract ：
受降雨作用，球状风化花岗岩类土质边坡的土-岩差异风化界面极易演化为优势渗流通道而发生渗流潜蚀，进而加速该类边坡的变形失稳，然而当前有关其渗流潜蚀作用特征、细颗粒迁移规律等的研究仍鲜见开展。基于多孔介质非饱和渗流理论，综合考虑细颗粒运移、潜蚀启动响应与非饱和渗流的耦合关系，提出一种可准确描述土-岩界面渗流潜蚀过程的数值计算框架。采用有限元方法，构建优势流作用下非饱和花岗岩残积土的渗流潜蚀模型，并以均质土柱的渗流潜蚀过程为参考，系统研究3种典型土-岩界面埋藏状态下的优势流潜蚀特性。结果表明：球状风化花岗岩类土质边坡的土-岩界面与基质渗透性存在高度差异性，湿润锋形成向下凹陷的渗透漏斗，且随着降雨的持续，湿润锋的凹陷程度愈发明显；细颗粒流失程度与土-岩界面的埋藏状态相关，其中下填土体工况的优势流潜蚀最为显著，其界面处甚至出现超孔隙水压力，最不利于该类边坡的稳定性。研究成果可为降雨条件下球状风化花岗岩类土质边坡稳定性的准确评价提供科学依据。
