摘要
介绍了粘弹性人工边界以及粘弹性人工边界单元的推导过程,在此基础上对某重力坝的坝体—地基结构系统进行有限元三维地震响应分析,结果表明无限地基辐射阻尼的粘弹性人工边界能够显著减小坝体地震响应。
This paper has deduced the viscous-spring artificial boundary and viscous-spring artificial boundary element, then study the dam-base of gravity dam by three-dimensional nonlinear seismic response history analysis. It shows that the viscous-spring artificial boundary with radiation damping can reduce the seismic response of dam obviously.
