| 摘 要： | 飞来峡水利枢纽位于北江中游,新建的二、三线船闸并列布置有效尺度为220 m×34 m×4.5 m(长×宽×门槛水深),船闸最大设计水头14.44 m,采用闸底长廊道侧支孔输水系统双明沟消能布置形式。通过1∶30的物理模型,对船闸输水系统的布置形式及水力学特性进行试验研究。结果表明:闸室输水时间、水力学指标、闸室停泊条件、进出口布置形式均能满足规范要求,优化后的闸室停泊条件较好。

| Abstract: | The water conservancy project of Feilaixia located in the middle reaches of Beijiang river.The new second & third-lane locks are arranged parallely with the effective dimensions of 220 m×34 m×4.5 m (length×width×threshold depth),and the maximum design head is 14.44 m,using lock-bottom long-culvert & side-hole water conveyance system and layout pattern of energy dissipation with double open ditches.Carrying out an experimental study on the layout pattern of the conveyance system and hydraulic characteristics through the model test in 1:30 scale,we draw the conclusion that chamber delivery time,water hydraulic parameters,chamber berthing conditions,import and export of layout pattern can meet the specification requirements.It has been optimized to better conditions for the berthing chamber. |
