摘　　要：受制于山区峡谷地形条件,迷宫堰宫数选择有限。通过水工模型试验,研究一定堰高下的W型迷宫堰过流能力。随着堰顶水头的增加,迷宫堰过堰水流的流态逐渐从薄壁堰流向真空实用堰流过渡。与之对应,迷宫堰过流能力增长幅度小于WES实用堰。基于堰流基本公式,对试验研究成果进行数学回归分析。在此基础上,通过比尺放大,分析流量系数的变化,得到可直接用于实际工程的W型迷宫堰流量系数计算公式。Subject to the mountain canyon terrain conditions, maze weir palace numbersare limited. Through the hydraulic model test, this paper studied on flow capacity of W type labyrinth weir, With the increase of water head at weir cres, the flow of the labyrinth weir was gradually flowing from thin -walled weir to vacuum. Corresponding to the maze weir over- current capacity, growth rate was less than WES practical weir. Based on the basic formula of weir, the mathematical regression of experimental research results was carried out. On this basis, through the scale amplification and the analysis of flow coefficient changes, the calculation formula of W - type maze weir flow coefficient could be directly used for practical engineering.
