Earthquake response analysis of Pubugou corewall rockfill dam

To build high earth- rockfill dam on thick cover foundation in high earthquake intensity region will face many problems such as dynamic stability,dam foundation liquefaction etc. It is highly necessary to carry out dam's seismic dynamic response to provide the guidance for design and construction of the dam. As an example,three-dimensional dynamic FEM was employed to analyze the seismic response of Pubugou corewall rockfill dam. The earthquake resistance capacity of corewall and seepage proof wall,and the liquefaction possibility of foundation sand layer were researched. According to the analysis results,some optimized measures for dam structure,material,and so on,were put forward to improve the seismic resistance of Pubugou corewall rockfill dam. The conclusions drawn in this paper can provide a reference to similar engineering.
