| 摘要: |
| 结合富春江船闸改扩建工程具体条件,根据《船闸输水系统设计规范》的相关规定及要求,在对比分析大量资料的基础上,确定了富春江船闸输水系统型式及具体布置,重点研究了进水口布置方案,并进行了1∶30比尺的物理模型试验研究.结果表明,新船闸采用闸底长廊道输水系统布置型式是合适的,通过老船闸上闸首进水口及其闸室共同进水的方式是可行的,研究确定的阀门开启方式,船闸输水时间、船舶停泊条件及进出水口水流条件等水力指标满足设计及规范要求. |

| Abstract: |
| According to specific characteristics of ship lock reconstruction project on Fuchunjiang River and the relevant rules of "Design Code for Filling and Emptying System of Shiplocks",on the basis of analyzing a great number of references,a type of the filling and emptying system and a detailed layout are put forward in the paper.The layout of the water inlet is especially studied and physical model tests(scale 1:30) are finished.The study results show that the layout of the new shiplock’s lock bottom longitudinal culvert filling and emptying system on Fuchunjiang River is suitable.And a scheme of the water inlet is reasonable through the old shiplock’s inlet and its lock chamber.Hydraulic indexes such as the filling or emptying time,vessel’s berthing conditions and flow conditions at the inlet and outlet can all fulfil design and criterion demands if the recommended open modes of the valve are adopted. |
