摘要
采用有限元对观音水库重力坝的安全进行复核,得到大坝各工况下的结构应力、变形及坝基抗滑稳定安全系数,并与传统材料力学法和刚体极限平衡法的计算结果进行对比验证,证明大坝设计的正确性和合理性。对于坝基软弱结构面、坝体局部孔口削弱部位,有限元分析的成果也为后续设计提供了依据。
The safety of the Guanyin Reservoir gravity dam was reviewed using finite element method to obtain the structural stress,deformation,and anti-skid stability safety factor of the dam foundation under various working conditions.And compare and verify the calculation results with traditional material mechanics methods and rigid body limit equilibrium methods to prove the correctness and rationality of the dam design.The results of finite element analysis also provide a basis for subsequent design for the weak structural planes of the dam foundation and the weakened parts of the local openings of the dam.
