西气东输管道工程EJ065号桩附近山涧跨越边坡稳定性分析

ASSESSMENT ON THE SLOPE STABILITY OF THE SPAN FROM EJ065+1 TO EJ065+2 ON THE LINE OF GAS TRANSPORTATION PROJECT WEST TO EAST

摘要: 通过野外地质调查确定研究区的区域地震活动、工程地质条件和受力边界条件,采集样品进行测试获取岩体的基本物理力学指标,在此基础上进行不同条件下(天然、饱和、震动力)的边坡三维模拟定量分析,评价边坡的稳定性,提出工程建议。

Abstract: Based on the investigation of regional seismic activity, engineering geology conditions and rock masses loading boundaries, and on the physical and mechanic parameters tested indoor, this paper use three dimensional (3-D) numerical model to evaluate the stability of the slopes and afford suggestions to engineering construction in three cases (natural state, saturated state, saturated and shaking state.
