摘　　要：对于二维有压渗流问题,采用有限差分方法进行数值模拟,用映象点法处理非规则边界,并绘出流网,与电模拟试验进行对比,验证了这种方法的可行性。The method of simulating the problem of two-dimensional pressure seepage with the method of finite difference, disposing the anomalous boundary by mapping point method and protracting the current net was carried out. By comparing the result with that of electronic simulation experiment, the feasibility of this method was proved.
