摘　　要：目前岩质崩塌稳定性分析方法众多，从大的方面分为：定性方法和定量方法。定性方法有地质条件分析法、工程地质类比法和图解法等；定量分析方法有极限平衡法、有限元法和数值计算方法等。文章介绍了赤平投影法的基本原理，应用岩体结构分析法对典型的岩质崩塌进行稳定性评价。At present time, methods for stability analysis of rocky collapse are numerous. The method is divided into qualitative and quantitative methods in major terms. Qualitative methods include analysis of geologic condition, engineering geological analogy, graphic method and so on; quantitative methods include limit equilibrium method, finite element method, numerical calculation method, etc. The basic principle of stereographic projection method is introduced and evaluated of rocky collapse stability through rock structure is analysis in the paper.
