| 摘要: |
| 兴隆船闸采用短廊道输水系统,属集中输水系统布置中的中高水头船闸.船闸规模及一次充泄水水体大,输水时间短,水力指标要求高.对于输水系统出口设置在闸首的船闸,其充、泄水系统出口布置型式以及输水阀门的运行方式直接影响过闸船舶安全.通过1∶30兴隆船闸整体模型,对过闸船舶停泊条件等关键水力学问题进行了专题研究.通过研究提出了能够满足充泄水时间和停泊条件要求的输水阀门运行方式及输水系统布置型式,为兴隆船闸设计提供了科学依据,并可作为其他短廊道输水系统船闸设计参考. |

| Abstract: |
| Xinglong shiplock adopted a short gallery emptying system,which belongs to one of the mid-high head shiplocks in the arrangement of the water delivery system.For its large scale and huge water volume discharge in short time,strict hydraulic indexes are required.As the water inlet of water convey system is arranged in the forward direction of the shiplock,the water filling and emptying arrangement gives impacts on shiplift operation.Key hydraulic problems such as vessel berthing conditions are studied through Xinglong Lock 1∶30 integral model.The water filling and emptying arrangement satisfying vessel berthing is found,which provides the scientific basis for Xinglong shiplock design,and can provide references for the design of other short gallery emptying systems. |
