| 摘 要： | 乐山市境内某井场平整形成填方边坡.边坡坡脚井场污水池开挖中,临空面和边坡支挡工程均出现变形破坏.根据变形破坏的分布规律,从场地地形、建筑物分布、边坡特征和原始坡体物质结构方面,分析该边坡变形机理,评价其稳定性影响因素.并采用极限平衡法对边坡的稳定性及下滑推力进行计算.在此基础上,针对性地提出该边坡的工程处治方案,保证后期井场及污水池的作业安全.

| Abstract: | Afill slope has occurred in the construction of JS1 well site in Leshan City.Deforms and failures have occurred at the free surfaces and supporting constructions during the sewage pool construction.Deformation mechanism and stability-affecting factors are analyzed in terms of topography,building distribution,slope characteristics and original slope structure.The limit equilibrium method is used to calculate the slope stability and the slide-thrust force.Then corresponding engineering measures are proposed to guarantee the security in the late well site and pool construction. |
