边坡工程系统稳定性薄弱部位的预测与控制

Prediction and Control of Weak Parts for Stability in Slope Engineering System

基于岩体工程失稳的“突破观点”，采用块体理论方法预测了某复杂边坡工程系统进口顺层边坡的薄弱部位——块体系统分布，在监测分析边坡块体系统动态稳定性的基础上，提出了边坡加固处理方法．根据有限元数值模拟与位移监测分析，预测确定了该边坡系统出口“上硬下软”逆向边坡的稳定性薄弱部位及控制因素，并对这些薄弱部位的加固方法及效果进行了分析．

On the basis of breakthrough point of stability loss in rock mass, key block theory is used to forecast the block system of the inlet bedding slope in a slope engineering system, which is the weak parts for stability. Based on the dynamic stability monitoring of block system, the reinforcement method of inlet slope is put forward. According to finite element simulation and monitored displacement analysis, the weak parts and the influence factors of exit converse slope with the characteristics of rockmass distribution i.e, upper stratum is hard and the lower is soft, are predicted and determined, then the reinforcement methods and results for the weak parts for stability are analyzed.
