摘　　要：运用特征线法研究南水北调工程天津干线输水系统的水力过渡过程,建立了复杂边界条件的数学模型,分析了进口闸流量变化所产生的非恒定水流对明流段、调节池及满流段水力特性的影响,以及由此引起的暗渠输水流量的变化特性,为工程设计及正常运行提供依据．The method of characteristics is applied to study the hydraulic characteristics of South-to-North water diversion middle route project in Tianjin. The mathematical model of complex boundary conditions is set up. The impacts of the unsteady flow caused by the varying flow rate on the hydraulic characteristics of open-channel flow, the surge tank and the pipe flow and the varying flow rate of the culvert caused by them are analyzed, thus providing academic guidance for the design and operation of the project.
