| 引用水管网计算原理将电阻网模型程序化，不仅能更精确、迅速地获取电阻网模型上各地下水渗流问题的解答，还能模拟计算非达酉流和城市自来水管网流量的分配。沿用矩形网络计算电阻值的等效面积单元的方法，并推广到三角形网络，以计算任意不规则网络的问题。最后，给出了规则裂隙组二维和不规则岩体裂隙三维问题的算例。 |

| Abstract: |
| Based on the principle of calculating pipe networks in hydraulics the model test on electric resistance networks is compiled by a computer program which can be used to solve not only the groundwater seepage problems more accurate and fast but also the discharge distribution problems of pipe networks in city water supply. As an example for each type of problems has been computed by this program and the results of which are in conformity with that of model test on networks. With the method of an equivalent area element to simulate the resistor value of rectangular meshes in resistance networks we extend it to triangular networks and then easily apply to any irregular networks. As a consequence the seepage problem in rock fractures can be solved by this program and some calculating examples of 2-D with regular fractures and 3-D with irregular fractures in rock masses are given. |
