山区高速公路软质岩路堑顺层滑坡机制及整治方案研究

在路堑边坡的工程勘察设计过程中，岩层产状是路堑边坡稳定性的关键因素之一，软弱结构面的强度指标对顺层岩质边坡的稳定性起主要控制作用。以某绕城高速公路某处软质岩顺层边坡工点为例，在工程地质勘察清楚、现场调查资料详尽的基础上，对该顺层滑坡采用了坡脚路堑挡土墙、中部设置抗滑桩、坡面锚杆框架梁防护及完善排水设施等综合整治设计方案，顺层滑坡处置效果良好。

Study on the Mechanism and Regulation Scheme of Soft Rock Cutting Bedding Landslide on the Expressway in Mountainous Area

In the process of engineering survey and design of cutting slope, attitude of rocks is the critical factor for the stability of cutting slopes. The strength index of weak structural plane plays an important role in controlling the stability of bedding rock slope. Taking an example of a soft rock bedding slope of a circle city expressway, this design adopted such comprehensive regulation design schemes as setting retaining wall in the toe of bedding slope, setting anti-slide pile in the middle of bedding slope, setting anchor frame beam on the slope and perfecting drainage facilities to protect the bedding landslide on the basis of clear engineering geological survey and detailed spot investigation data, which obtained good results in the treatment of bedding landslide.
