Mesh Generation for 3-D Dynamic Analysis of Fill Dam
The purpose of this study is to examine the effects of a degree of discretization in the direction of longitudinal dam axis and the effects of a size of analysis region on the results of three dimensional fill dam dynamic analysis.In this study,the three dimensional dynamic analyses of the existing Hoengseong dam in Korea which was modeled with a different degree of discretization and a different size of analysis region were carried out.From these results,the fundamental frequencies of the dam and the responses at the dam crest such as acceleration and settlement were compared with each case and analyzed.It was concluded that the size of finite element discretized in the direction of the longitudinal axis must be smaller than 1/8 of dam length in order to obtain the reasonable settlement behaviors from the three dimensional dynamic analysis of the fill dam. Also,it was concluded that the effects of the size of analysis region on the amplification of acceleration at the crest and the fundamental frequency of the dam were negligible in case that the free field boundary condition was applied.
