高速公路炭质页岩高边坡稳定性分析及施工方案

Stability Analysis and Construction Scheme of Expressway Carbonaceous Shale Slope

在炭质页岩高边坡地区,较易出现失稳、滑塌等现象。对此,明确具体的地质特性,并采取合适的加固措施和排水措施,可有效提高高速公路的运营水平。以龙怀高速公路工程为依托,阐述了炭质页岩具有的易风化、强度低等工程特性,对沿线炭质页岩高边坡的稳定性以及施工方案进行分析,以期给类似工程提供参考。

In the area of high slope of carbonaceous shale,it is easy to appear instability and slump.In this regard,clear specific geological characteristics,and take appropriate reinforcement and drainage measures,can effectively improve the expressway operation level.Based on the Longhuai expressway project,this paper expounds the engineering characteristics of the carbonite shale with easy weathering and low strength,and analyzes the stability and construction scheme of the high slope along the carbonite shale,in order to provide reference for similar projects.
