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.
