哈达山水利枢纽上下游通航连接技术*

针对松花江哈达山枢纽未建设过船设施,枢纽上下游不能连续通航的问题,采用水流数学模型研究哈达山—松原滚水坝河段通航水流特征。采用实测资料对模型进行验证,对河段现状水流情况进行模拟,分析现状河道通航水流特性,对解决哈达山枢纽上下游通航的连接技术的方案进行模拟研究,得出具体通航水流特征指标。结果表明,采用建船闸和枢纽上下游建码头的技术方案,解决了哈达山枢纽上下游连接通航问题,可为类似工程提供参考。

Navigation connection technology for upper and lower reaches of Hadashan hydro-junction

In order to solve the problem that the upper and lower reaches of Hadashan hub of Songhua River cannot be continuously navigable without any navigational facilities,we use the water flow mathematical model to study the navigation flow characteristics of the reach from Hadashan to the Songyuan rolling dam.We validate the model by measured data,simulate the current status water flow of the river,analyze the navigation flow characteristics,simulate and study the scheme of connecting the upstream and downstream navigation technologies of the Hadashan hydro-junction,and obtain the navigation flow characteristic parameters.The results show that it can be solved that navigation problem of upstream and downstream connection for Hadashan hydro-junction by technology scheme of constructing ship lock or port in the upstream and downstream of the hydro-junction.It can provide references for the similar projects.
