Abstract

A kind of fixed grid method of alteration transmission coeffident 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.
