拱坝-地基系统的三维非线性地震反应分析

【摘要】 本文将显式有限元结合外推人工边界的方法发展应用于三维非线性近场波动问题的研究，首次提出了拱坝库水地基系统三维非线性地震反应波动分析方法，并与传统的无质量地基分析方法进行了比较更多还原

【Abstract】 In this paper,the combination of explicit finite element method and transmitting boundary method is developed to study the three dimensional non linear wave problem in the near field.The seismic response wave analysis method for non linear arch dam foundation system is given and compared with the traditional massless foundation method.更多还原
