结合北运河杨洼闸的改建设计,对杨洼闸进行模拟试验,分析平原河道上平底板闸门的泄流能力。并与设计计算进行比较,试验结果表明,闸孔全开时可以选用《水闸设计规范》推荐的水闸泄流能力计算公式;部分闸孔开启,泄流能力需由模型试验确定。
Combining with the reconstruction design of Yanglu sluice of Beijunhe River, a simulation test of Yangla sluice was carried out to analyze the discharge capacity of flat bottom sluice gate in plain river. The test results show that when the gate is fully open, the formula of sluice discharge capacity recommended by Code for Design of Sluice Gate can be selected. The opening of some gates and the ability of discharging are determined by the model test.
