| 摘 要： | 为探讨平原河网区配水方案,以慈溪市城河河网为例,在对城河河网进行概化处理的前提下,以表征明渠水流基本运动规律的圣维南方程为理论依据,结合具体的边界条件和初始条件,采用水力计算软件求其数值解.并根据不同计算方案下的数值模拟成果,对不同控制条件下"同时配水"方案与"轮流配水"方案进行了分析,从防洪控制水位要求以及断面平均流速变化情况入手,对不同配水方案下的河网水力特征模拟结果进行分析,旨在为进一步实施城河河网的调水配水工作提供参考依据.

| Abstract: | Taking the urban river network of Cixi as an example and on the premise of a generalized river network,based on Saint-Venant equations which indicate the basic laws of open channel flow,combining specific boundary conditions and initial conditions,we use hydraulic calculation software to obtain numerical solutions.In accordance with the results of numerical model,the schemes of simultaneous water distribution and rotation water distribution are analyzed from two aspects : the requirements of the flood contr... |
