摘要
利用拉格朗日法推导了两种常用明渠最优水力断面的通用表达式，并对梯弧形和梯形进行了对比分析，结果表明：梯弧型具有较好的水力经济性。
Abstract General formulation of best hydraulic channel section was proposed by Lagranage's method,And comparative analysis was made between round bottom triangular section and trapezoidal section, Result shows that round-bottom triangular section has better hydraulic and economic.
