三峡工程泄洪深孔体型及掺气设施研究

本文综述了二十余年来对三峡工程泄洪深孔体型开展的试验研究工作,包括深孔有压段体型、陡槽方案、突扩跌坎式掺气设施、跌坎掺气设施等.研究成果不仅为三峡工程泄水建筑物体型设计和施工提供了依据,也加深了对坝身泄水建筑物体型水力学问题的认识,并为类似水工建筑物体型设计提供了宝贵的研究成果.

Overview on hydraulic design of the flood-release deep outlets of Three Gorges project

This paper gives an overview on the hydraulic design studies of the deep outlets of Three Gorges dam during the past 20 years. These studies cover the selection of the sizes and shapes of pressurized tunnel section,spillway chute,bottom offset aerator,and abrupt expansion of lateral walls. These studies are crucial to the design and construction of these flood - release outlets and valuable to the designs of similar hydraulic works,and they shed light on the general concepts of the related hydrodynamic phen...
