| 摘要: |
| 我国河流地貌丰富多样,分汊河流较多,渠化工程布置困难.多汊河流在进行河道通航渠化过程中,需要在枢纽布置、航线规划和通航水流条件等方面进行综合考虑.本研究以浙江衢江安仁铺航电枢纽为例,采用整体物理模型试验,研究多汊河流上航电枢纽的航线规划、航道整治及枢纽运行调度等关键技术难题.比较了枢纽上游多条航线的通航水流条件,给出了最佳航线和船舶航行安全条件;针对下游航道两岸过渡的特点,提出了下游航道优化布置方案和整治范围.结合枢纽合理运行调度,较好地解决了该枢纽的整体通航问题,可为类似工程提供借鉴. |

| Abstract: |
| It is difficult to canalize project on multi-branch rivers.The project layout,route planning and navigation flow conditions and other aspects need comprehensive consideration.Taking the Anrenfu navigation-hydropower project of the Qujiang River in Zhejiang Province for example and based on the overall physical model,the route planning,channel regulation,operation scheduling and other key technical problems of the project at a multi-branch river is studied.Comparing the flow conditions for a number of routes in the upstream,this paper gives the best route and ship navigation safety conditions;According to the characteristic of the channel transition of the bank on downstream channel,the optimal layout scheme and regulation range of downstream channel is proposed.By means of reasonable operation and scheduling,the whole navigation problem is perfectly solved. |
