某高等级公路反倾向层状高边坡倾倒变形分析

Analysis on Toppling Deformation of Anti-dip Stratified High Slope on High-grade Highway

摘要:

倾倒变形是山区反倾向层状岩质边坡失稳的典型模式之一，以某高等级公路连接线反倾向岩质高边坡变形破坏为例，通过对高边坡的坡体结构和岩体结构分析及建模理论计算，进行边坡倾倒机理研究，并对边坡的稳定性和破坏形式进行了客观评价。在此基础上提出了相关工程处置措施，对类似岩质边坡的分析防治有一定的参考作用。

Abstract:

Toppling deformation is one of the typical instability modes of anti-dip stratified rock slope in mountainous areas. Taking the deformation and failure of anti-dip rock high slope of a high-grade highway connection line as an example， the slope toppling mechanism is studied through the analysis of the high slope structure and rock mass structure and the modeling theory calculation. The stability and failure form of the slope are objectively evaluated. On this basis, the relevant engineering treatment measures are put forward, which have a certain reference for the analysis and prevention of similar rock slopes.
