草街二线高水头船闸模型试验研究

Study on High-lift Lock Model Test of Caojie Navigation and Hydropower Project Line 2

在嘉陵江草街船闸水力学模型试验研究基础上,首次提出并论证了高水头船闸单侧主廊道、闸底横支廊道输水系统的合理布置,确定了其输水系统的布置型式。试验结果表明,这种新型布置形式可以有效解决船闸水力指标要求高和地形布置条件特殊的技术难题,研究成果可为类似实际工程提供科学依据。同时,这种新型布置型式拓宽了我国高水头船闸单侧廊道输水系统布置的应用领域,发展了高水头单侧廊道输水系统船闸水力学研究的水平。

In this text,the rational arrangement of high head lock side main corridor and lock bottom horizontal corridor water conveyance system of Caojie navigation and hydropower project is put forward and demonstrated based on the lock hydraulic model test so as to determine the layout of water conveyance system.The results show that the new layout can effectively resolve the technical problems of high hydraulic index of lock and special topography,and provide scientific reference for similar projects.Meanwhile,the new layout pattern broadens the application scope of high-head lock side corridor water conveyance system in China,and also increases the hydraulic study level of locks.
