摘要
建立了贺江白沙至江口区段航道一维河网数学模型,采用该模型对贺江航道进行模拟分析,深入研究了水库不同调度条件下贺江航道断面水深问题。计算结果表明,贺江航道自白沙至江口区段的整体状况良好,只有在枯水期和中水期工况下在都平闸下存在不满足通航要求的区段,并且距离短、易整治。最后给出了不符合航道设计尺度要求的断面区间及其断面类型,对整体的贺江模型模拟计算结果进行了分析,提出了整治意见。
One dimensional numerical model from Hejiang Baisha to Jiangkou is built and used to simulate the Hejiang channel and analyze the sectional water depth under different sehedulings. The calculation results show that the whole situation of Hejiang channel from Baisha to Jiangkou is favorable. The channel behind Duping ship lock has the region which does not meet the navigation requirements only in the condition of low water and middle water period, the distance is short and it＇s easy to control. The channel section intervals and section types which don＇t satisfy the demand of channel＇s design dimensions are given and the simulation result for whole Hejiang channel is analyzed and opinions on channel＇s regulation are put forward.
