Parameter Inversion Analysis of Shuikou Gravity Dam Body Based on Improved Particle Swarm Optimization Algorithm

Aiming at the defect of local convergence in the traditional particle swarm optimization,the particle swarm optimization is improved and the hybrid model of dam deformation safety monitoring is established based on the dam prototype observation data and finite element calculation.The modulus of elasticity of the concrete dam body and its foundation and the horizontal displacement of dam crest are calculated by the improved particle swarm optimization.Compared with the measured values,the proposed method is reasonable and feasible.Furthermore,it has small error and high precision.
