摘　　要：河道水面线计算中的分段求和法需要事先确定开始计算断面的控制水深。为此,采用了根据河道断面资料先计算临界水深和正常水深,再结合12种水面曲线的规律确定控制水深的方法。应用结果表明,该方法适用于无直接控制水深资料的非棱柱体明渠水面线计算。In order to determine the controlling water depth of the start cross-section of river for the calculation of water surface profile with need partition summation method,a procedure is proposed to calculate firstly the critical depth and normal depth based on the river cross-section data and then consider the hydraulic law of 12 kinds of surface curves.The application of the procedure shows that it is applicable to the calculation of the non-prismatic open channel water surface profile even if the controlling depth data are not available.
