| 摘 要： | 滑坡发育机制的核心是滑动带在压剪荷载作用下的断裂扩展。将土质滑坡滑动带贯通过程分为初始裂纹、裂纹扩展、裂纹后缘闭合三个阶段。对滑坡破坏模型运用断裂力学、极限平衡理论,建立了滑坡破坏机制的力学分析方法。通过三峡库区故陵滑坡计算实例,证明了计算方法的可行性。

| Abstract: | The core technology of landslide development is failure mechanism of sliding zone under compression and shear loads.The coalescence process of soil landslide sliding zone is divided into three stages: initial crack,crack propagation,crack closure of trailing-edge.Mechanical analysis method of landslide failure mechanism is established using fracture mechanics and limit equilibrium theory based on landslide damage model.Through the example of Guling Landslide in Three Gorges Reservoir Area,the calculation me... |
