渠江金盘子船闸输水系统水力学原型观测研究

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:该船闸进出口、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...

Hydraulics Prototype Observation on Conveyance System of the Jinpanzi Power Station in Qujiang River

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 observation results show that the import,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 coefficients 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 simulated model,therefore,its corridor suction pressure value exceeds the requirements of specifications.Finally,suggestions for improvement are proposed.
