摘要
通过对双支点复合运动式水力自控翻板闸门的运转机理和受力平衡的分析,讨论了水力自控翻板闸门在多泥沙河流与清水河流上应用的不同,推导出最高启门水位条件下翻板闸门能正常翻转的闸前临界淤沙高度公式,通过算例得到最高启门水位下闸前临界淤沙高度值,进而得出临界淤沙高度与门顶启门水位的关系,为分析淤沙压力对多泥沙河流水力自控翻板闸门的影响提供依据。
different application of hydraulic automatic control flap gate between in sandy and clear river is discussed by analyzing its rotational mechanism and forces balance,educes the critical sediment height expressions in the front of flap gate under the maximal water level and gains the critical sediment height value though an example.Then it receives the connection between the critical sediment height and water level on the flap gate.The results serve as a basis for analyzing the effect of sediment pressure on hydraulic automatic control flap gate in sandy rivers.
