摘要
西江航运开发采取上游渠化航道,下游整治的方针.“七五”期间建设了桂平枢纽,改善航道110km.“八五”期间建设贵港通航枢纽,1997年截流通航,渠化航道104km.桂平至西津之间43个滩险,除地伏滩、伏波滩和鸡儿滩需进行不同程度的整治外,都已满足通航尺度要求.西津电站1964年建成,水位60.60m以上回水可达南宁,但这种水位机率小.西津水库原设计死水位为59.62m.变动回水区内有著名的浅滩洴滩,建库以后,水沙条件改变。
The properties of hydrology sediment, fluvial process and forming causes of various shoals of the Xijiang River (Guangxi Rearch) are analyzed; the successful experience in regulating the channel obstructed by the shoals is summarized; and finally, the calculation method for the width of regulation line is presented.
