摘　　要：太浦河是太湖洪水的骨干排洪河道,也是太湖向下游供水的骨干河道,其主要功能是承泄太湖洪水和杭嘉湖涝水,兼有防洪、排涝、供水、灌溉、航运、旅游、改善水环境等多种功能。本文主要通过河道一维水力学数学模型,用四节点Preissmann格式解完整的圣维南(de Saint Venant)方程组,计算出不同洪水频率(5a、20a、50a一遇)下的太浦河河道各节点的水位和流量,分析了太浦河沿岸各侧向入流对其的影响,为太浦闸的调度提出了一些意见。Taipu river is the backbone flood passage and water supply channel of Taihu lake with its main function of discharging flood of Taihu lake and waterlogged areas of Hang-Jia lake, also with multiple functions of flood control, drainage of waterlogged areas, water supply.irrigation, shipping, tourism and water environment improvement. This paper deals one dimensional hydraulic mathematic model of Saint Venant equations with Preissmann difference scheme to compute water level and discharge along Taipu river under different flood frequencies combinations （one in 5-year flood, one in 20-year flood and one in 50-year flood）, and analyses the influence of lateral inflow along Taipu river, ultimately has given some suggestions for the regulation of Taipu Gate.
