Integrating Finite Element Method with GAs to Estimate the Scour Depth of Bridge

Chung-Wei Feng, Hsun-Yi Huang, and Shen-Haw Ju
Abstract—Bridge scour is one of the major reasons to cause bridge failure and bring serious disaster. As a preventive against disaster the scour depth around a bridge pier is an important index to evaluate the condition of the bridge. However, to detect the scour depth around bridge piers is hard task since the bridge foundation is under water. In this study, an approach which combines finite element method and genetic algorithms is used to estimate the bridge scour depth via the variation in the natural frequency of the bridge structure and conduct a genetic formula for scour bridge. In this paper, soil strength and pile length compare with natural frequency within different bridge scour depth is discussed. And to exam the approach, two types of bridge pile arrangement are used.

Index Terms—Bridge scour, finite element method, genetic algorithms, natural frequency
