基于强度折减法的高路堑边坡稳定性分析

Stability analysis of high slope based on strength reduction method

为确保某主干线公路高路堑边坡施工安全,基于强度折减法对边坡的稳定性进行数值分析,分析结果表明：该路堑边坡安全系数范围大致为1.07~1.08,极易失稳产生滑坡,并从边坡的塑性区演变过程可以初步推断,该路堑边坡可能产生推移式滑坡。建议采取相应的加固措施对边坡进行加固处理,避免工程安全事故的发生。

In order to ensure a trunk road cut high slope construction safety and strength reduction on the slope stability based on numerical analysis, the analysis results show that： the slope safety coefficient range is roughly the 1.07~1.08, very easy to lose stability of landslide, and from the slope of the plastic zone evolution can be inferred that the cutting slope may have lapsed landslide. Suggestions take corresponding reinforcement measures on the slope of reinforcement, avoid the occurrence of safety accidents.
