| 摘 要： | 对节点虚流量法进行了改进,严格扣除过渡区中虚流量贡献,使虚流流量的处理在理论上更严密,关键的溢出点位置计算更精细.提出在全部渗流区域的迭代算法,避免了以往算法在迭代过程抛弃虚单元、计算域网格发生变化的做法,从而使算法编程更简单,使用范围更广.算例验证了该算法的正确性和实用性.

| Abstract: | To improve the procedure of nodal virtual flux,the virtual flux is deducted rigorously and theory of the disposed nodal virtual flux is further perfected.The key overflow location calculation is especially accurate.It improves modus operandi of abandoning the false element and changing region of net happenning in the past law iterative process,lets calculation happenning in global seepage region.Then,it makes the algorithm programming simpler and application range to expand more.The correctness and practica... |
