Abstract

Abstract: The stereographic-real proportion projection method has a unique advantage in the stability analysis of the rock slope. In the case study of a certain rock slope in Heishangu, the comprehensive analysis of the slope was carried out by adopting the stereographic-real proportion projection method. The important features such as sliding mechanism, sliding direction, sliding surface area and sliding body volume were analyzed. And the rock slopes stability was also analyzed by the stereographic-real proportion projection method. The advantages and disadvantages of the stereographic-real proportion projection method and the transfer coefficient method in the traditional limit equilibrium method were discussed. The results show that the stereographic-real proportion projection method has more advantages than the transfer coefficient method in the analysis of rock slopes stability, which can provide reference for the protection of rock slope.

Key words: geotechnical engineering, stability analysis, rock slope, stereographic projection, real proportion projection

摘要： 赤平极射-实体比例投影方法在岩质边坡的稳定性分析中具有独特的优势。以黑山谷某岩质边坡为例，采用赤平极射-实体比例投影对该边坡进行了综合性分析，分析了滑坡的滑动机制、滑动方向、滑面面积、滑体体积等重要特征，并通过赤平极射-实体比例投影方法对该岩质边坡的稳定性进行了分析，讨论了赤平极射-实体比例投影方法和传统极限平衡法中的传递系数法的优缺点，认为赤平极射-实体比例投影法在岩质边坡稳定性分析中比传递系数法更具有优势，该方法能够为岩质边坡的防护提供参考。
