| 摘 要： | 在对乌东德拱坝进行动力时程分析过程中,考虑了坝体—库水—地基的动力相互作用和地基法向边界面上采用粘-弹性人工边界条件两方面的影响,与常规无质量地基模型的计算结果对比,流固耦合和地基辐射阻尼能使坝体的动力响应值分别降低20%和15%左右,地基辐射阻尼对乌东德拱坝动力响应的影响不显著。

| Abstract: | Effects of dam-water-foundation dynamic interaction and using viscous-spring artificial boundary condition on the normal bounding surface of the foundation have been considered in the course of the seismic response analysis on Wudongde arch dam.The calculation results present that,compared with the conventional method of fixed boundary with no weight foundation,the value of seismic response separately decreases by about 20% and 15% considering fluid-solid coupling and foundation radiation damping,and the influence of the latter factor is not prominent on the dynamic response of Wudongde arch dam. |
