基于ABAQUS的深覆盖层地基面板堆石坝 防渗墙应力与变形分析

结合某深厚覆盖层上的面板堆石坝工程实例,基于有限元分析软件ABAQUS,采用三维非线性有限元数值分析法,对其静力工作形态进行了深入的研究,并针对此工程总结了修建于深覆盖层上的高混凝土面板堆石坝应力变形的一般规律,论证了此大坝结构设计的合理性,为设计和施工提供了理论依据,同时,也为深覆盖层上面板堆石坝的动力特性分析提供一些前期准备.

Study on the Stess and Stain of CFRD Penetrate Walls on Deep Overburden Foundation Based on ABAQUS

Up till now, due to the seismic stability and good adaptability, concrete face rockfill dam has become preferred type of the dam built on deep overburden layer. In this article, based on ABAQUS, combined with practical concrete face rockfill dam project, by using three-dimensional nonlinear finite element numerical analysis method, the seismic proprieties have been studied. Then the general rules of high concrete face rockfill dam on deep overburden layer ground have been summarized, which provids reasonable proofs for design and consteuction. In addition, this word also laid a solid foundation for dynamic analysis.
