摘要
根据碾压混凝土坝的结构特点,运用四参数、Mohr-Coulumb和Drucker-Parger准则分别模拟坝体、层面和基岩的非线性特征,并以渗流水压力和位移为未知数,建立坝体渗流场与应力场耦合的弹塑性有限元分析模型,探讨了拟定碾压混凝土坝变形二级监控指标的方法。
According to the structure characteristics of roller compacted concrete dam, the elastic-plastic finite element model is set up considering seepage-stress coupled. In this model, four-parameter criterion, Mohr-Coulumb criterion and Drucker-Prager criterion are used to simulate the nonlinear feature of the dam body, the bedding joint and the foundation. the seepage-pressure and displacement are considered as indeterminate number. At last, the secondary monitoring index of roller compacted concrete dam's deformation is made.
