基于改进粒子群优化算法的施工期拱坝结构性态反演分析
Inverse analysis of structural behaviors of arch darns during construction period based on improved partiche swarm optimizatinon
摘要
Abstract
For their deformation characteristics, a special safety monitoring model for arch dams during the construction period was established. Trie hydraulic component of the dam deformation was extracted. The improved particle swarm optimization method was employed to optimize and calculate the optimal control model for inversion problems of arch dams. Accordingly, the inverse analysis of structural behaviors of arch dams during the construction period would be performed. An arch dam was taken as an example to inverse its structural behaviors during the construction period. The results show that the relative errors of the inversed dam deformation are all less than 2%, and the feasibility of the proposed method is validated.关键词
