高落差、陡坡泄槽水流流速较高，易形成自掺气水流，水深加大。如果对掺气水深估计不足，泄槽边墙高度不够，将会威胁建筑物的安全。利用某渣场排水系统泄槽沿程掺气水深的计算分析，比较了常用的几种掺气水深计算方法，并与模型试验成果对比。本例中王俊勇公式与模型试验成果接近，泄槽完建后运行良好。

In steep chute with a great fall , the water flow velocity is usually high and self -aerated flow tends to occur . The water depth in the chute will increase accordingly .If the side wall is not high enough because of the underestimation of the aerated water depth , safety of the structures will be threatened .In this paper , several calculation formulae for aer-ated water depth that are commonly used are compared with a chute example in the drainage system of a residue field . Model test results are also given and serve as the benchmark .It shows that the calculation result from Wang Junyong for-mula is close to the test results .The chute is then built following the results and a good performance is shown .
