摘　　要：目前梯形渠道横断面设计主要采用试算法和图解方法,计算效率不高。对现有试算方法进行了改进,便于利用计算机进行试算,另外给出了设计水深计算的迭代方法。最后给出了基于试算法和迭代法的FORTRAN程序,设计结果表明,上述方法简单有效。Try and error method and graphic method are routine methods for design of trapezoidal canal cross section at present despite of their low efficiency. Two methods are suggested for trapezoidal canal design in order to improve design efficiency. One is an try and error method improved suitable for computer program, another is an iterative method. Two FORTRAN programs based on the principles are also given to determine design depth. The results indicats that the methods are simple and effective. 
