| 摘 要： | 由于边界单元法只需在边界上剖分单元，且容易处理无限边界问题，所以在计算坝基面渗透压力时较有限元法具有明显的优势。介绍了坝基面渗透压力的计算理论及其边界元数值算法，并给出了应用算例。由算例分析可以看出，采用边界元法计算坝基面渗透压力，计算程序简单，占用计算机内存少，计算速度快，且计算精度较高。

| Abstract: | Because the boundary element method divides its elements on its boundary and is easy to deal with the infinite boundary problem, it has obvious advantages in calculating seepage pressure on dam foundation surface over the finite element method This paper describes the calculation theory of seepage pressure on dam foundation surface and its boundary element numerical calculation methods and gives some case studies The results showed that using the boundary element method to calculate seepage pressure on dam foundation surface has the advantage of easy calculation program, quick calculation speed and high calculation accuracy |
