Numerical Solution Analysis of Nonlinear Seepage Domain in Continuous Media

土石坝的非线性渗流求解在于渗流自由面和溢出面的确定。文章基于移动网格法、单元渗透矩阵调整法和复合单元高斯点法,运用Microsoft Developer Studio可视化集成开发二维无压渗流分析有限元程序,结合具体算例求解连续介质渗流区域的非线性问题,成果对渗流区域非线性问题研究具有重要意义。

The solution of nonlinear seepage flow for earth and rockfill dams lies in the determination of seepage free surface and overflow surface.Based on the moving mesh method and the composite element Gaussian point method,Visual integration of Microsoft Developer Studio was used to develop two-dimensional finite element program for seepage analysis in this paper,a numerical example is given to solve the nonlinear problem of seepage flow in continuous media,and the results are of great significance to the study of the nonlinear problem of seepage area.
