| 摘 要： | 自由面位置的确定是无压渗流计算的一个关键环节.求解这类问题的方法有固定网格法和移动网格法,但目前大部分都用固定网格法来解决自由面的位置问题,本文采用边界元通过移动网格法来求解自由面的位置问题,而在迭代过程中对溢出点采用二次插值的方法来确定.该方法思路清晰,易于编写程序,计算结果也比较精确,完全能够达到工程建设所要求的精度.

| Abstract: | Determinating the location of the free surface is a key step in seepage flow calculation.There are two methods to solve these problems :One is fixing-grid method,the other is changing-grid method.But most persons use the fixing-grid method to determinate the location of the free surface at present.In this paper, we use the boundary element method(BEM) and changing-grid method to determinate the location of the free surface,during the iteration process,using the quadratic interpolation to determinate the loc... |
