摘要
西津水利枢纽二线船闸工程对发展西江航运和流域经济具有重要作用。为研究二线船闸布置方案与原一线船闸布置的相互影响,采用水工模型试验研究二线船闸下引航道两类不同布置方案下的水流条件,通过分别测定一、二线船闸下引航道口门区纵、横向及回流流速三项指标,并进行对比分析得知:一、二线船闸下引航道口门区采用共用布置方案时,在中洪水流量情况下,口门区内横向及回流流速难以满足规范要求;当采用下引航道口门区分开布置形式时,二线船闸下引航道口门区多项流速在各级通航流量下基本满足规范要求。
The second-line ship lock project of Xijin Water Conservancy Project plays an important role in the development of the Xijiang River shipping and watershed economy.In order to study the interaction between the second-line ship lock layout and the layout of the original ship lock,hydraulic model test was carried out to study the water flow conditions under two different layout schemes,by comparing the three indices of longitudinal,transverse and backflow velocities of the first and second line ship lock gates.The comparative analysis shows that when using the common layout scheme of the first and second shiplock gateways,in the case of flood flow,the horizontal and return flow velocity in the area can’t meet the standard requirements.When using the next navigation channel door to separate the type of layout,flow velocities of the second-line lock under the entrance area of the lower approach channel at all levels of navigation traffic basically meet the code requirements.
