Study on flood discharge and energy dissipation type of Zhala Hydropower Station
摘要
Abstract
The head junction of Zhala Hydropower Station has the engineering constraints of an asymmetric narrow valley,com-pact building layout,complex geological conditions,and requirement of ecological flow.Combined with the characteristics of the project,two energy dissipation schemes of ski-jump and underflow are preliminarily proposed.The flow pattern,pressure charac-teristics,flow velocity and riverbed erosion under two different schemes were analyzed by a hydraulic model test.At the same time,the building layout,water atomization,construction condition and technical-economic conditions under the two schemes were also compared.The results showed that the underflow energy dissipation scheme had sufficient energy dissipation,small atom-ization and scouring,excellent building layout,less influence by flood discharge and better construction conditions.Although the e-conomy of the underflow energy dissipation scheme was slightly worse than that of the ski-jump scheme,it had better safety and adaptability.Finally,the underflow energy dissipation scheme was selected as the recommended flood discharge energy dissipation scheme.The relevant results can be a useful reference for the design of flood discharge and energy dissipation of similar projects.关键词
