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。
n this paper,the combination method of explict finite element method and transmitting boundary method is developed to apply to studying of three-dimensional non-linear wave problem in the near field.The seismic r espouse wave analysis method of three-dimensional non-linear arch dam-water-foundation system is firstly given and it is compared with the traditional massless foundation method.
