西江梧州水文站设计最低通航水位探讨

Design lowest navigable water level of Xijiang Wuzhou hydrological station

根据西江控制站梧州水文站多年历史资料及近期实测资料,在分析梧州设计水位变化特征的基础上,采用推算设计流量和下游设计水位,以数学模型计算工程前后设计水位的方法,综合考虑枢纽坝下河床下切、潮汐作用、工程疏浚等因素影响,计算分析西江长洲枢纽坝下3000吨级航道工程的梧州水文站设计最低通航水位,为附近工程建设及类似航道整治项目相关设计水位取值提供参考。

According to the historical data and recent measured data of Wuzhou Hydrological Station of Xijiang River Control Station,based on the analysis of the variation characteristics of Wuzhou design water level,this paper calculates the design flow and downstream design water level,and the design water level before and after the project by the mathematical model.Considering the influences of riverbed undercutting,tidal action,engineering dredging and other factors under the dam of the hub,this paper calculates and analyzes the design lowest navigable water level of Wuzhou Hydrological Station for the 3000-ton waterway project,so as to provide reference for setting relevant water levels for nearby project construction and similar waterway regulation.
