大型渠道工程规模的优选方法

The optimization method for capacity of large-scale canal

应用系统工程和渠道设计的理论与方法，研究了大型骨干渠道工程设计流量和加大流量的优选问题，为今后研究大型渠道工程的规模提供了理论依据和设计方法．该方法已用于研究南水北调中线工程总干渠．

The optimal capacity of large-scale canal including the design discharge and the extended discharge of the canal is studied by applying the principle of system engineering. The primary factors which influence the canal capacity have. been analyzed and a multi-step optimal design method for canal capacity has been established. The method has been applied to the design of the canal in middle route of South-to-North water transfers for Yangtze River. The results are satisfactory.
