摘　　要：针对采用拟静力法计算水工建筑物地震作用效应时由于分层多造成质心和质点的动态分布系数求解困难的问题,根据工程实践总结提出了优化分层的简化算法。算例分析结果表明,采用优化分层的简化算法完全可以满足设计要求,是求解水工建筑物地震作用效应的一种便捷方法。It is difficult to solve the mass center and the dynamic distribution coefficient due to the multiple layers when the quasi-static method is applied to estimate the seismic effect of hydraulic structures.This paper presents a simplified algorithm for the hierarchical optimization based on engineering practice.The case study indicates that the simplified algorithm can completely meet the design requirements and is a convenient method for estimating the seismic effect of hydraulic structures.
