摘要
通过对顶山隧洞进出口水工模型试验研究,验证隧洞进出口各种工况下的水流流态和消力池的消能效果及水流对下游渠道可能产生的冲刷影响;试验测得隧洞进出口水流流态基本平稳,隧洞出口的消力池末端流速不大,不会对下游渠道产生大的冲刷破坏。
Through the hydraulic model test about import and export of Hill Top Tunnel to verify the flow conditions of the stilling basin of import and export in all kinds of tunnel and the effect of energy dissipation and the possible impact of the erosion of flow channels on the lower reaches;tunnel test measured the basic steady flow in the import and export,tunnel stilling basin export terminal velocity is not and will not have a great impact on the downstream channel erosion damage.
