摘要

The artificial fish swarm algorithm adopts a new top-down way of thinking, starting from the realization of individual behaviors of artificial fish and then reaching the global optimum of the group through the local optimization of fish individuals of the group. Based on the finite element analysis software-MSC. Marc, this article makes inversion analysis for mechanical parameters of dam. By combining the monitoring data of a dam, inversion analysis is made on the elastic modulus of the dam body, dam foundation, both dam shores and the fault fracture zone by using the artificial fish swarm algorithm. Results show that using artificial fish swarm algorithm to make inversion analysis on dam mechanical parameters not only has faster convergence rate but also have higher accuracy.
