龙羊峡水电站中孔事故闸门门槽空化性能研究

Cavitation Characteristics on Emergency Gate Slot of Middle Oulet at Longyangxia Hydroelectric Power Station

在中孔常压模型试验的基础上，进行减压试验以验证事故检修门槽的空化性能。根据减压试验成果及前人研究资料，对影响闸室段空化性能诸因素门槽体型尺寸，空化与空蚀的控制标准等进行了综合分析。上述成果可对高水头压力泄水短管的设计、运行提供有益的参考。

Based on atomspheric hydraulic medel test of middle outlet,the subatomspheric medel ismade to test and vetify the cavitation characteristics. According to the subatomspheric test and previousinformation,various factors,such as configuration of gate slot and cavitation control rules, are anal-ysed synthetically in this paper.These results are useful to the design and operaton of intakes for highhead pressure discharge conduit.
