水利工程基础设计地基承载力的确定与分析

摘要

The stability problems of a hydraulic engineering generally stem from the deformation of the foundation and the received bearing capacity.The foundation deformation in general is not arbitrary,but the hydraulic structures of load transfer to the ground through the foundation,making natural soil of original stress state changes,i.e.in the basal pressure,leading to additional stress and vertical,lateral and shear deformation and resulting in the ettlement and displacement of the building and its surrounding environment.%水利工程地基的稳定性问题一般都源于地基的变形强度和其所受承载力等因素。其中地基的变形一般不是人为确定的，而是水工建筑物荷载通过基础传递给地基，使天然土层原有的应力状态发生变化，即在基底压力的作用下，地基中产生了附加应力和竖向、侧向或剪切变形，导致建筑物及其周边环境的沉降和位移。
