| 摘 要： | 基于刚体理论和整体极限平衡原理，建立力学传递模型，分析滑坡在崩塌体堆积作用下的稳定性，建立链式计算关系，最终可确定滑坡破坏的极限阈值。以重庆市李子坝一化龙桥危岩滑坡为例，对该计算理论的正确性进行验证，结果表明该计算理论能很好地反映在崩塌体堆积作用下发生滑坡灾害链的实际情况，且具有较高的计算精度，可以为此类问题提供借鉴和参考。

| Abstract: | Based on the rigid-body theory and the principles of limit equilibrium,the model of mechanical transmission is built and the stability of landslide under the accumulation of the collapsed is analyzed. The theory for collapses and landslide disaster chain is established,thus determining the limit threshold of landslide damage. Based on the results of Liziba-Hualongqiao slope in Chongqin,the accuracy of this theory is validated and the results show that this theory could better reflect the actual situation of... |
