Optimization design research on the impervious curtain structure based on improved PSO algorithm

Abstract

In this study, the impervious curtain structure of riverbed part of the concrete face rockfill dam (CFRD) is optimized. This method is based on the particle swarm optimization (PSO) algorithm and combines with finite element method to calculate the seepage discharge of dam foundation in riverbed part at different depth and thickness. The result shows that the seepage discharge decreases with the increase of curtain depth, and the effect of curtain thickness on seepage discharge is not obvious. This is an effective and practical method to solve engineering problems that meeting the requirement on structural stability and satisfy the economic.
