缓倾层面条件下炭质泥岩夹层高边坡处治研究

Study on Treatment of High Slope of Carbonaceous Mudstone Interlayer under Gently Inclined Surface

炭质泥岩具有风化快、强度低、遇水崩解严重等不良地质特征。其是路堑公路边坡工程中常见的一种控制性软弱夹层,如何处治由此所引起的边坡滑移,是确保边坡稳定安全的关键因素。基于贵州省某高速公路炭质泥岩夹层路堑边坡的处治案例,对边坡失稳成因、防护方案、动态处置措施、边坡位移监控量测分析等进行综合研究,为类似工程地质条件下的路堑边坡治理提供参考。

The carbonaceous mudstone is characterized by bad weathering, low strength, severe disintegration,etc. It is a common controllable weak interlayer in the cutting road side slope project,treat side slope slide there from is the key factor for side slope stability and safety. In this paper,the treatment case of carbonaceous mudstone interlayer cutting side slope of certain expressway in Guizhou Province is used to study the side slope instability cause,protection scheme,dynamic treatment measures,side slope displacement monitoring measurement analysis,so to provide reference for cutting side slope treatment under similar engineering geological conditions.
