摘　　要：从河道水面线计算求解过程中水力半径和糙率引发的问题出发,提出了一种新的概化河道断面方法,并对该方法进行了实例验证。验证结果表明该方法满足水文分析计算要求,计算结果合理可信。The paper starts from hydraulic radius and roughness,which is a difficult problem in water surface line calculation.Based on this problem,a new generalization method is proposed. The method is analyzed by resistance transformation,and also the simulation result is vivificated. The new method willsimplify the calculation of water surface line.
