摘要
面板堆石坝的变形分析是复杂的三维“非连续变形”问题。针对这一问题,对MSC.Marc有限元程序进行了二次开发,发展了三维子模型法,模拟了面板3个方向的边界、复杂的材料分区与施工过程,对目前世界最高的水布垭面板堆石坝进行了数值仿真,有效地解决了目前存在的数值分析精度偏低的问题。
Deformation analysis for concrete faced rockfill dam （CFRD） is a complicated 3D “discontinuous deformation” problem. For solving the problem, a MSC. Marc FEM program was redeveloped and a 3D submodel method presented. The method was used to make a numerical simulation for stress and deformation of Shuibuya CFRD, the highest CFRD in the world at present. The boundary of face slab in three directions, complicated material zoning and construction process were dealt with in the simulation. The problem of lower accuracy in the numerical analysis in CFRD was effectively solved.
