—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.
—Bridge scour, finite element method, genetic
algorithms, natural frequency
