泥化夹层对边坡工程稳定性影响及控制方法研究

岩体边坡工程的稳定性往往由岩体结构 (尤其是泥化夹层 )所控制 ,因此边坡工程一般需对控制边坡稳定的主要结构面进行控制处理 .以某边坡工程系统进口顺向及出口“上硬下软”逆向岩石边坡为例 ,分析了泥化夹层对边坡稳定的控制作用 ,介绍了采用洞挖方式设置混凝土阻滑键及采用混凝土置换泥化夹层以改善边坡稳定性的方法 ,通过阻滑键内、置换体内及边坡的实际应力、应变监测 ,分析了这两种加固处理方法对改善边坡稳定性的作用 ,提出了有待解决的问题

Influence of Mudded Intercalation on Slope Stability and Its Controlling

The stability of rock slope engineering is generally controlled by rock structure,especially the mudded intercalation,so it is needed to control the main rock structure in slope for the purpose of stability improvement. Taking as an example a consequent-bedding rock slope and a converse complex rock slope with hard limestone, as the upper part and the soft shale as the lower part, the control of mudded intercalation on slope stability was analyzed, the control method of resistance sliding key and concrete replacement for mudded intercalation was introduced, and actual action analysis of resistance sliding key and concrete replacement on slope stability improvement was done through the monitoring information of stress and strain in resistance sliding key, concrete replacement and slope, problems to be solved were put forward.
