复杂加载条件下高面板坝应力变形有限元分析

摘要

采用非线性有限单元法，对某高混凝土面板堆石坝进行复杂加载条件下的应力变形仿真分析，揭示了面板堆石坝在各种工况下的应力变形规律，为工程设计提供了依据。%Nonlinear finite element method ( FEM) is applied to analyze the stress and deformation of a high CFRD which will be constructed under complex loading mode .The law of stress and strain of CFRD in different operational states is revealed .The re-search thus provided a basis for engineering design.
