摘　　要：运用特征线法研究引滦入津工程新建州河段暗渠水力过渡过程,建立了复杂边界条件的数学模型,采用不同的时间步长处理明流段暗渠缓流与临界流的过渡断面,计算因电站机组运行台数变化所产生的非恒定水流对明流段暗渠、调节池及满流段暗渠水力特性的影响,以及由此引起的暗渠输水流量变化特性,为工程设计及正常运行提供依据。In this paper, the method of characteristics was applied to compute hydraulic transients in newly built Zhouhe River Conduit Project, part of Water Diversion Project from Luanhe River into Tianjin. The mathematical models were set up aiming at complex boundary conditions and different time step was used to deal with the conjunction boundary of tranquil flow and critical flow. The hydraulic properties of unsteady flow caused by varying water turbine units in operation are studied, including hydraulic properties in open-channel flow, surge tank and pipe flow, thus providing academic guidance for the design and operation of the project.
