摘要
渗流自由面的确定是无压渗流分析中非常重要的问题。相对有限无法而言，采用边界元法确定渗流自由面具有明显的优势。本文基于传统的确定渗流自由面的迭代边界元法，提出了改进的采用边界元法确定充自由面的失窃 工方法，并运用算例说明了改进方法的精度和有效性。
The determination of seepage free surface is one of the key issues in the seepage analysis. The boundary element method (BEM) has some advantages over the finite element method, especially for solving the free surface only. Based on the traditional BEM method, a modified iterative method for solving seepage free surface by BEM is proposed and examined in this paper.
