摘要
文中以G4216仁沐高速不等厚互层顺层滑坡典型工程为例,进行了滑坡成因机制分析及边坡稳定性评价,针对高边坡、不等厚顺层边坡、产状变化为特征的路堑边坡提出了分段设计、固脚强腰、分级(分层)逐级、坡体整体稳定兼顾局部边坡稳定的治理思路。实践证明,设计方案取得了较好的治理效果,为同类型边坡提供了设计思路,尽量规避工期风险与投资风险。
This article takes a typical project of G4216 Renmu Expressway with unequal thickness bedding landslide as an example to analyze the mechanism of landslide formation and evaluate slope stability.For cutting slopes characterized by high slopes,unequal thickness bedding slopes,and changes in occurrence,segmented design,foot reinforcement,waist strengthening,and grading(layering)are proposed The overall stability of the slope and the treatment concept of considering local slope stability.Practice has proven that the design scheme has achieved good governance results,providing design ideas for the same type of slope,and trying to avoid construction period and investment risks as much as possible.
