乌依布拉克二级水电站溢洪道挑坎设计方案比选

Comparison and Selection of Cantilever Design Schemes for Spillway of Uybrak Secondary Hydropower Station

泄水建筑物承担着水库多余水量的安全宣泄功能,对水库的安全运行至关重要,其布置方式和体型设计是水利工程研究领域的重要课题。以新疆维吾尔自治区乌依布拉克二级水电站为例,通过方案比选的方式对大圆弧导向鼻坎设计进行模型试验研究,采用大圆弧导向曲面贴角鼻坎设计,能够加强挑坎对水流的导向和分散水舌作用,对相关水利工程具有一定借鉴作用。

The water discharge building bears the safe releasing function of the excess water volume of the reservoir,which is very important for the safe operation of the reservoir. Its layout and body design are important topics in the field of hydraulic engineering research. Taking the UYBRAK II Hydropower Station in Xinjiang Uygur Autonomous Region as an example, the model test study on the design of large arc guiding nose ridge is carried out by means of scheme comparison. The design of large arc-guided curved surface nose can enhance the picking The guiding of water flow and the role of dispersing water tongue have certain reference for related water conservancy projects.
