Graphic Template for Analysis of Rock Slope Stability by Stereographic Projection Method

岩质边坡的变形和破坏主要受岩体中发育的结构面控制。采用赤平投影方法对岩质边坡的稳定性进行分析,可以方便地确定边坡岩体中结构面的相互组合关系,以及结构面组合切割体可能失稳滑移的方向,从而能定性评价边坡的稳定状态。采用赤平投影方法分析岩质边坡的稳定性时,基于"结构面组合交线的倾向和倾角"2个因素,总结设计了赤平投影法分析岩质边坡稳定性的图解模板。借助赤平投影图解模板进行边坡的稳定性分析,使问题变得更加直观、明朗,分析工作更加简化、快捷。通过工程实例的应用,进一步验证了图解模板用来分析岩质边坡稳定性的有效性、实用性和便捷性。

Deformation and failure of the rock slopes are mainly controlled by the structural planes developed in rockmass. Analysis on stability of the rock slopes by the stereographic projection method can easily determine the relationship of mutual combinations of the structural planes in the slope rockmass as well as the sliding direction of the cutting mass of the structural plane combination which may destabilize so as to qualitatively evaluate the stability of the slopes. When the stability of the rock slopes is analyzed by the stereographic projection method, dip and dip angle of the intersection line of the structural plane combination shall be based. Furthermore, the graphic template for analysis of rock slope stability by the stereographic project method is summarized and concluded. With help of the graphic template, the slope stability can be analyzed directly and clearly. The analyzing work becomes simple and convenient. Through practice of the template in actual work, effect, practice and convenience of the graphic template for the analysis on the rock slope stability are veri fied further.
