韩江上游(梅江、汀江)航道整治工程试验研究

Study on the engineering of channel regulation in upstream Hanjiang River

韩江上游梅江蓬辣滩、汀江青溪两日调节枢纽坝下游河道,由于电站无基流下泄,只能利用发电流量通航。该河段来水来沙条件复杂,为达到V(3)航道,因而需通过定床物理模型试验进行航道整治研究。利用恒定流验证非恒定流的方法,对模型进行了验证。然后,针对特殊来流条件下碍航特点提出整治方案,研究表明工程效果良好,且长河段全线挖槽和筑坝对水位的影响很少。这一研究为类似枢纽坝下通航提供参考。

The navigation must depend on the discharge by generation of electric energy, because there is no small generating unit in Penglatan and Qingxi Hydraulic Power Plant to adjust discharge. In order to achieve the V（3） channel standard, the channel below dam must be researched by fixed bed model test because of the complex flow conditions. The method of simulating the unsteady flow by the steady flow was presented, and it was used in the model. Then the regulation plan was suggested in the particular flow conditions, which can be referred to the similar engineering.
