摘要: 本文讨论了非均匀介质自由边界问题的边界元解法,导出了具有弱奇性积分核的边界积分方程,并被用来处理分片均匀土坝的渗流自由面问题。

Abstract: In this paper we discuss the boundary element method for solving the free boundary problems of non-uniform media. A boundary integral equation with integral kernals of weak singularity is presented with its application to the seepage tree boundary problem in which the eartbdams are piece-wise homogeneous.
