| 摘 要： | 在分析汊点分组解法的基础上,提出了汊点分组解法的一般理论和算法。新方法的特点是可将河网汊点分片编码处理,而且汊点分组后可通过适用于一般分级解法的原汊点水位关系得到新的汊点方程组,新方法的通用性较好,值得推广应用。

| Abstract: | This paper discussed the juntions group method initially put forth by Li Yitian in datail,and advanced a new method,which can be applied in wide practices and is worth being recommended.The advantage of the new method is that the coding works of junctions can be handed in each sub-area individually,and the water level equations of junctions group can be obtained directly by using the original relations among junctions suitable to the common gradation method. |
