【摘要】 通过对百色水利枢纽消力池的三维整体有限元计算 ,分析了不均匀地基上消力池的沉降与应力特征。根据消力池键槽“传剪传压不传拉”的特性及结构缝的工作机理 ,建立了键槽单元的非线性分析模型 ,并对比研究了不均匀地基上键槽布置方式对消力池应力与变形的影响 ,提出了合理的结构缝键槽布置方案更多还原

【Abstract】 By integrity three-dimensional finite element calculation, settlement and stress is analyzed for the stilling pool on uneven foundation. In view of the key groove of stilling pool transferring shear and pressure except tensile force as well as the working mechanism of structural joint, a nonlinear analysis model is established for the key groove element, different arrangement modes of the key grooves on uneven foundation and their effect on the stilling pool stress and deformation is also compared and studied. Based on above a reasonable structural joint and key groove arrangement proposal is figured out.更多还原
