摘　　要：复式断面明渠中,二次流对水流特性具有重要的影响。现有复式断面横向速度分布的分析解模型中,对二次流的表示有多种形式。针对其中两种常用的考虑二次流影响的分析解模型在梯形明渠中的应用,采用FCF(Flood Channel Facility)的实验数据对模型进行了检验,结果表明两种模型各有利弊,具体应用中需根据实际情况进行选择。Secondary currents have important effects on the flow in compound channels.The secondary flow term has different style in different type of analytical model for solving the lateral distribution of depth averaged velocity.Two typical analytical models have been adopted for comparison,and the experimental data of FCF（Flood Channel Facility） were used for validation.The result shows that both models have advantages and disadvantages,and during practical applications,cautions should be taken to make sure that good results can be obtained.
