摘要
岩质边坡稳定性判别是一个综合性问题。边坡稳定性评价包括定性分析、失稳模式判别和定量分析等方法。定性分析方法有SMR法、CSMR法,依据赤平投影法对边坡的失稳模式(如平面滑动、楔体破坏、倾倒破坏)做出相应判别;定量分析则是根据上述的3种不同失稳模式选择不同的评价方法。本文对岩质边坡稳定性评价方法作了综述分析,并介绍了陈祖煜提出的一种三维刚体极限平衡分析法。
Rock slope stability discriminant is a comprehensive problem. Slope stability evaluation includes qualitative analysis, instability mode of judgment and quantitative analysis methods. Qualitative analysis methods of slope stability evaluation include the SMR method and CSMR method that can make corresponding discrimination of instability mode like plane sliding, wedge damage, titling failure by using the stereographic projection. Different Quantitative analysis methods of slope stability evaluation were selected according to each instability mode. This article is an overview on the evaluation methods of rock slope stability, and a three-dimensional rigid body limit equilibrium analysis proposed by Z. Y. Chen is introduced.
