| 摘 要： | 基于液固两相介质的Biot固结理论,应用饱和多孔液固两相介质的波动方程,研究淤沙对拱坝的地震响应大小。把淤沙模拟成塑性材料,分析淤沙层厚度、凝聚力和摩擦角对拱坝地震响应的影响程度。通过算例分析表明,淤沙对拱坝坝体地震响应的影响较为显著。

| Abstract: | By Bait's consolidation theory,pressure wave equation of saturated porous fluid-solid medium was applied to prediction of the seismic response magnitude of arch dam.Thickness,cohesion and friction angle of the sediments were considered to analyze their effects on the response.Application of the method to a typical example shows a significant effect of sediments. |
