| 摘 要： | 着重考虑了闸上下游行近段的河道形态对水流结构的影响,即当行近水流流向偏离水闸纵向轴线时,回流、过闸水流的不对称等将降低水闸的过闸能力.根据观澜河大和水闸的实验结果,分析了回流、过闸水流的不对称等影响闸孔过流能力的规律.在此基础上,根据实验结果,给出了修正的计算公式,检验结果表明所建立的修正公式较适用大和水闸过闸流量的计算.

| Abstract: | The influence of the channel forms near the sluice's upperstrem and down stream on the flow structure is mainly considered, i.e., when flows direction of the progressive flow departure the sluice lognitudinal axis, back flow and asymmetry of the flow through the sluice will decrease the water discharge. The laws of the back flow and its asymmetry that influences the discharge have been analyzed based on the experimental data of Dahe sluice at the Guanlan River. The experimental results show that the modified calculation formula of the water discharge of Dahe sluice is reasonable and has enough accuracy. |
