摘要
变电站建设作为输变电工程关键节点之一,边坡的稳定是确保变电站安全运营的关键。高挖深填边坡的稳定性分析以及支护方案研究是需要解决的技术难点。为保证某变电站高挖深填边坡的稳定性,避免边坡变形甚至破坏导致的不利影响,以现场工程地质调查、地质勘探的方式揭露场区工程地质特征,对高挖深填边坡建立地质模型,采用刚体极限平衡和有限元数值模拟开展定量计算,对稳定性系数达不到规范要求的边坡提出合适的治理措施。
Substation construction as one of the key points of power transmission and transformation project,the stability of slope is the key to ensure the safe operation of substation.The stability analysis and support scheme research of high excavation and deep filling slope are technical difficulties to be solved.In order to ensure a high substation digging deep to fill slope stability,avoid the negative impact of the slope deformation and destruction caused by field engineering geological survey and geological prospecting way to expose engineering geological characteristics in jobsite,dig deep fill slope geological model is set up on high,the rigid body limit equilibrium and finite element numerical simulation to conduct quantitative calculation,The appropriate treatment measures are put forward for the slope whose safety factor fails to meet the requirements of the code.
