摘要
Abstract
Duncan-Chang E-B model is used to simulate rockfill mass. Contact between face slab and cushion layer is simulated by interface element. Face slab vertical joints and peripheral joints are simulated by crevice element. 3D FEM deformation-stress analysis was conducted for Tianchi face-slab rockfill dam to calculate the displacement,stress and their distributions of rockfill mass and face slab. Deformation of slab vertical joints and peripheral joints were analyzed. The results of calculation indicate that displacement and stress of dam body are all within rational range, and the deformation of slab joints and peripheral joints meets the static requirements.关键词
