摘要
以察汗乌苏面板堆石坝有限元法应力变形计算结果为基础,总结了在深覆盖层地基上建造的面板堆石坝的关键技术。根据对三峡二期深水土石围堰拆除的调查实录进行的分析认为,实录对面板坝防渗墙的计算有重大参考价值。提出引进新的数值方法,如不连续变形分析方法(DDA)和数值流形方法(NMM),来模拟和计算面板坝接缝变形的设想,对深覆盖层上面板堆石坝的设计和计算有指导意义。
Based on calculated finite element deformation results of Chahanwusu, the key technology of concrete face rockfill dam built on thick alluvium deposits is summarized. The site investigation records of second cofferdam of Three Gorges Project that has great reference value on numerical calculation of diaphragm wall of CFRD is also discussed in this paper. Finally, the idea of using new numerical method such as Discontinuous Deformation Analysis （DDA） and Numerical Manifold Method （NMM） to simulate the joint of CFRD is proposed, which can make guidance on the design and calculation of CFRD built on thick alluvium deposits.
