摘　　要：采用边界元法分析了多种正交各向异性介质渗流问题,建立了问题的间接变量规则化边界积分方程.数值实验表明;该算法稳定、效率高,所取得的边界量数值结果与精确解相当吻合.In this paper,seepage flow problems with zoned orthotropic medium are solved by the boundary element method（BEM）.The computational theory of osmotic pressure on the dam foundation is introduced briefly,and the regularized boundary integral equations with indirect unknowns,which don＇t involve direct calculation of CPV and HFP integrals,are established.The convergence and accuracy of the proposed algorithm are investigated with several numerical examples,demonstrating that a better precision and high computational efficiency can be achieved.
