摘要
用有限元、边界元和无限边界元(FE-BE-IBE)在时域内的耦合模型分析了溪洛渡拱坝的动力响应,在分析中考虑了无限地基辐射阻尼,结果表明辐射阻尼对拱坝的动力响应有显著的影响。又研究了辐射阻尼的不同影响因素,如水位、地基弹性模量和不同地震输入等。
Seismic response of the Xiluodu arch dam is analyzed by a coupling method of finite elements(FEs), boundary elements(BEs) and infinite boundary elements(IBEs) in time domain. Effects of radiation damping of infinite foundation on dam response is investigated in the analysis. The results demonstrate that significant influence of the radiation damping on the structural response is verified. In addition, influences of several factors such as reservoir elevation, stiffness of the rock foundation and different earthquake input on the radiation damping are also studied.
