三峡库区董家湾高切边坡稳定性赤平投影解析

岩质边坡的稳定性主要受结构面的控制和影响,因此,了解边坡中各结构面的相互关系是进行稳定性评价的前提。赤平极射投影可将三维空间内的几何要素投影到平面上进行研究,用它来解析岩质边坡的稳定性具有独特的优势。基于此,文中介绍了赤平投影的基本原理和使用方法,对三峡库区一典型岩质高切边坡的稳定性进行了分析和评价,满足了工程的要求。

Analysis on Stereographic Projection of High Cut Slope Stability in Dongjiawan of Three Gorges Reservoir Areas

Rock slope stability is mainly subject to structural surface.Therefore,it is a precondition to understand the interrelation of slope structural surfaces for stability analysis.Stereographic projection can project geometric factors in three-dimensional space onto a plane for study,which has unique advantages in analysis of rock slope stability.For this,this paper introduces the basic principle and usage of stereographic projection and carries out analysis and evaluation of a typical high cut slope stability ...
