横观各向同性地基上的碾压混凝土重力坝应力应变研究
Stress-strain study of RCC gravity dam on transverse isotropic foundation
摘要
Abstract
RCC gravity dam has a simple structure,can be constructed conveniently,and is widely used nowadays.In practical engineering,foundation anisotropy problems are often encountered.In this paper,we used the finite element analysis software ABAQUS,took the slope dam blocks of a roller compacted concrete gravity dam as the basic computational structure,and established a 3D finite element calculation model of RCC gravity dam.Under the normal storage condition,six different calculation groups were set that have different ratios of horizontal to vertical elastic modulus.Through comparative analysis,we studied the material ratio range within which anisotropy needs not to be considered.关键词
