地震作用下土石坝抗震稳定的谱元分析
Spectral Element Analysis of Seismic Stability of Earth-rock Dam under Seismic Action
【摘要】 地震作用下土石坝抗震稳定性研究是一项涉及地震工程、结构抗震、地质工程、岩体力学等诸多学科的综合课题。谱元法是计算流体力学中一类特殊的方法,它把有限元法和谱方法相结合,兼具了有限元的处理边界和结构的灵活性和谱方法的快速收敛特性,同时极大地减少了计算时间和内存需求。
【Abstract】 The seismic stability of earth-rock dam under seismic action is a comprehensive topic related to earthquake engineering,earthquake-resistant structure,rock mass mechanics and so on.Spectral element method is a special method of computation fluid mechanics,which combine finite element method with spectral method,and it possess both the flexibility of finite element method and the property of fast convergence of spectral method,and memory requirement and CPU time are reduced obviously at the same time.
