摘　　要：通过数学推导 ,建立了弧底梯形明渠水力最佳断面水深、过水断面面积、水力半径等所有几何要素与水力要素的计算公式 ,并通过算例详细说明其水力计算方法 。Based on strict mathematical derivation, a formula is developed for calculation of geometric and hydraulic factors of optimum hydraulic section design of open trapezoid channels, such as water depth, area of discharge section, hydraulic radius, and so on. In combination with calculation examples, the method of hydraulic calculation is explained in detail, providing a theoretical basis for section design of channels of this type.
