基于三维弹粘塑性本构关系的节理单元在面板堆石坝中的应用

采用基于三维弹粘塑性本构关系[1]的节理单元[2]对面板和堆石体问的接触面、堆石体与岩体间的接触面、以及用边缝、垂直缝等特殊边界进行模拟和分析研究,编制了有限元计算程序,并结合实际工程问题,进行了三维有限元计算分析,得到了满意的结果,为工程单位进行施工和设计提供了依据.

The Application of the Joint Element based on 3D Elasto-viscoplasticity Constitutive in Concrete-Face Rockfill Dam

with based on the joint element of three-dimensional elastoviscoplastic constitutive relation,the interface between the panel and rockfill,rockfill and rock,the surrounding cracks and vertical slits have been simulated and analyzed and researched,and worked out finite element computing program,combined with practical engineering issues,the three-dimensional finite element analysis,have been satisfied with the results,and provides the basis for engineering design and construction.
