【摘要】 在分析其它计算渗流自由面方法的基础上提出了一种渗流分析的改变渗流系数的固定网格法,该法只需进行一次网格剖分,不人为干涉计算过程,完全通过程序迭代即可准确地求出自由面的边界。算例计算表明,该法具有程序处理简单、用户操作方便、计算结果准确等特性,一般迭代收敛很快。可应用于稳定和非稳定渗流自由面边界计算。更多还原

【Abstract】 A kind of fixed grid method of alteration transmission coefficient of seepage flow analysis is put forward on the basis of analyzing the other computation seepage. It only needs once mesh grid,isn’t intervened calculation process. The free surface boundary can be calculated precisely through program iteration. The examples show that the program is simple,the operation is facility and calculation is precise.Convergence of the method is very quickly.The method is suitable for stable and unstable seepage analysis.更多还原
