某水电站导流洞出口体型优化设计

Optimization Design on Diversion Tunnel Outlet of Hydropower Station

水力学模型试验能够验证水力学计算成果的准确性,为优化设计提供科学依据,是大中型水电工程施工导流设计过程中的重要参考依据。为避免导流洞出口水流对下游的冲刷,对导流洞出口消能措施进行了研究。本文通过物理模型试验的前后对比,得到导流洞出口体型优化建议方案。

Hydraulic model test is an important referenee for designing large and medium-sized hydropower projects,which can be used to verify the accuracy of hydraulic calculation results and provide scientific basis for optimizing the design.In this paper,energy dissipation measures to avoid the scouring at the diversion tunnel outlet have been studied.The optimization scheme of the diversion tunnel outlet is obtained by the hydraulic model test.
