摘要
某厂厂房基础场平开挖后,灰岩顺层岩坡坡脚被切削,3条泥化夹层相继沿边坡出露,夹层上覆岩体极有可能沿夹层下滑。通过运用极限平衡法和弹塑性有限元法对边坡治理前后进行了稳定分析,经多方案优化对比,在工程治理中,采用了阻滑键、预应力锚索、预应力锚杆、挂网锚喷和SNS拦石网等现代滑坡治理技术,从表观和深层监测资料看,分析方法正确,工程治理措施可靠有效,边坡处于稳定状态。
On the bottom of a limestone slope, rocks were excavated, and three interlayers appear in the face of slope. The rock mass above interlayer is most likely sliding. The limit equilibrium method and elasto-plastic finite element method were applied in the analysis on slope stability after and before comprehensive treatment. Anti-slide mass and pre-stress anchor cable technique were applied in the project to keep the slope stable.
