冲沟区域岩石高边坡卸载稳定性分析

Analysis on high rock slope unloading stability in gully area

以冲沟区域岩石高边坡挡墙基槽开挖工程为例,采用数值模拟分析法,研究了边坡卸载的稳定性问题,并提出了边坡开挖的支护措施,经现场验证,发现跳槽开挖在控制围岩变形和塑性区范围方面效果良好。

Taking high slope retaining wall trench excavation engineering in gully area as an example,applying numerical simulation analysis method,the paper studies slope unloading stability issue,and puts forward slope excavation bearing measures. Through in-situ examination,it finds out that trench excavation has great effect in controlling surrounding rock deformation and plastic region scope.
