摘要
采用一种用于不规则边界的有限分析五点格式的方法,对稳定渗流中的非均质各向异性问题进行了计算,给出了适用于非稳定渗流计算的有限分析五点格式,对均质非稳定土坝渗流进行了计算。与其他方法相比,不规则边界的有限分析五点格式具有良好的数值性能。
The new five-point element scheme of finite analytic method for Laplace equation in irregular domain is used to calculate the constant seepage flow in heterogeneous dam body. The 5-point scheme of finite analytic method is given to simulate the unsteady seepage flow. The calculated result fitted well with the one obtained by finite element method. It shows that the five-point element scheme of finite analytic method can be used well to simulate the seepage flow.
