| 摘 要： | 平面坡体渐进破坏模型旨在通过在坡体稳定性分析中引进渐进坡坏的概念,来较合理地考虑岩土材料的峰值强度和残余强度在稳定性分析中的不同作用。通过与其它稳定性分析方法进行比较以及实例应用研究,证明该计算模型可用于初步判断坡体稳定状态并估算其破坏变形范围。这一研究也说明了水对边坡破坏的重要作用。

| Abstract: | The aim of this study is to introduce the concept of progressive failure into the stablity analysis of slope. The peak strength and residual strength of rock and soil masses are reasonably consided to be different in its role in the stability analysis. The comparative study with other methods of analysis and practical examples show the proposed computational model can be used for preliminary evaluation of slope stdbility and estimation of scope of failure and instability. This study also shows the important role of water in the slope stability. |
