抚河疏山水利枢纽船闸通航水流条件研究

Navigable flow condition of ship lock of Shushan water conservancy project in Fu River

为满足水运需求,解决船闸引航道口门区受河段地形和涉河建筑物影响而导致的通航条件困难等问题,保障船舶安全通行,以抚河疏山水利枢纽船闸工程为例,采用数值模拟方法,对枢纽船闸上游引航道口门区通航条件进行计算分析,针对不良流态问题提出优化方案措施,并对方案前后枢纽通航条件进行对比分析。研究表明,调整船闸平面布置等措施对改善设计阶段的枢纽船闸上引航道口门区通航条件是有效的。研究成果可为抚河疏山水利枢纽船闸工程通航及其他类似河段工程提供技术支持。

To meet the needs of water transportation,solve the problems such as difficult navigation conditions caused by the river section topography and river-related buildings in the entrance area of the ship lock approach channel,and ensure the safe passage of ships,this paper takes Shushan water conservancy project in Fu River as an example,and uses numerical simulation method to calculate and analyze the navigation conditions of the entrance area of the upstream approach channel of the lock.Aiming at the problem of bad flow pattern,the optimization scheme and measures are proposed,and the navigation conditions of the hub before and after the scheme are compared and analyzed.The research shows that the measures such as adjusting the plane layout of the lock are effective in improving the navigation conditions of the entrance area of the upper approach channel of the lock in the design stage.The research results can provide technical support for the navigation of Shushan water conservancy project in Fu River and other similar river section projects.
