Seismic Analysis of Homogeneous Earth Dam and Optimization of Its Parameters Using Pso

Abstract

In this paper the dynamic behavior of the homogeneous earth dam (Iran), considering dam-foundation interaction, under normalized Manjil
earthquake- as input motion- has been studied. In order to assess the effect of the dam heights and the foundation widths, in the finite element
model on the earthquake response, various dam-foundation coupled models are analyzed by Plaxis, a finite element package for solving
geotechnical problems. In this research, the dam heights and the foundation widths has been chosen optimally using particle swarm optimization
(PSO) method. The simulation results indicate considerable differences in the seismic responses.
