汉江雅口航运枢纽船闸通航条件试验研究

采用整体物理模型试验对汉江雅口航运枢纽船闸上下游口门区及连接段通航条件进行研究。阐述设计方案工程布置条件下的船闸通航条件及影响因素,针对设计方案在通航水流条件方面存在的不足,提出在船闸上游连接段外侧布置圆弧形隔流堤及河床局部疏浚等优化工程措施,较好地解决了枢纽船闸通航问题。

Experimental study on shiplock navigation condition of Yakou hydro-junction in Hanjiang river

Based on the integrated physical model test,we study the navigation condition at the entrance areas of the shiplock approach channel and the connecting section of Yakou hydro-junction in Hanjiang river. The navigation condition of shiplock and influential factors under the engineering arrangement in design scheme are expounded. In view of the disadvantages of navigable flow condition which exist in the design scheme,we propose the optimized measures such as the layout of circular-arc separation levee on the lateral side of connecting section at the upstream of the shiplock and the local dredging in the channel bed.Experiments show that it is a good method to solve the navigation problem of shiplock in the hydro-junction.
