摘要： 为了研究高水头船闸原型与模型试验的差异，更好的积累高水头船闸原型运行经验，对渠江金盘子船闸输水 系统进行了水力学原型观测。结果表明：该船闸进出El、闸室内流态较好；闸室内船舶系缆力满足规范要求；闸室 充、泄水的流量系数较模型增大12％—16％ ，与国内、外船闸输水系统研究基本一致；由于泄水阀门开启速度远大 于设计和模型试验研究情况，因此，其廊道压力的负压值超出规范要求。并对此提出了改进意见。

Abstract: In order to study the differences between the simulation tests and prototype tests on the high water head of lock，and accumulate further experience on the operation of high water head of lock in the same time，the hydraulic prototype observation on conveyance system of Jinpanzi Power Station in Qujiang River is carried out．Prototype obser- vation results show that the impoa，export of the lock and the gate house have a fine flow pattern；the gate indoor ship mooring force meets the regulatory requirements：the flow coeficients of chamber filling and draining of are 12％～ 16％ larger than those designed in the model，which basically accords to the results got in domestic and foreign study of water supply system．The sluice valve opening speed is much greater than the designed one and the one got by the sim- ulated model，therefore，its corridor suction pressure value exceeds the requirements of specifications．Finally，suggestions for improvement are proposed．
