摘要
有限单元法计算混凝土重力坝的静力承载能力,得出重力坝的拉压应力和应变的变化情况及混凝土的开裂情况。计算结果表明应用有限元法模拟坝体的非线性混凝土材料以及复杂的边界条件和荷载组合情况,能更准确如实地反映重力坝的静力性能。
The finite element method calculate the bearing capacity of concrete gravity dam static,and concluded that the gravity dam and compressive stress and strain of the change of concrete crack situation and calculation results show that finite element method is applied to the simulation of nonlinear concrete dam body material and complex boundary conditions and the load combinations,more accurately reflect the static performance of gravity dam faithfully
