摘　　要：介绍了现行溢洪道水面线的分析及计算方法,进一步从实践和理论二个方面评述了现行溢洪道计算方法中关于控制断面水深确定所存在的主要问题,针对上述问题进行了水工模型试验研究,经过多种体型的对比试验,最后给出了在不同坡比情况下控制断面水深的新的计算公式。In this paper the author introduced the present analysis and calculating method of spillway water surface line, and further narrated and commented the main questions about the depth of water of the control section from two aspects of the practice and the theory which are exist in the present spillway calculating method. In order to solve those problems, the hydraulic model has been tested by making various configuration contrast model test. The final author produced the new calculating formula after having compared in the situation in the different slopes.
