| 摘 要： | 利用二维河流数学模型对管墅直江引水进行了通航的影响计算，分析表明，工程按照设计取水流量运营时，原航道的最大横向水流流速、纵向影响流速、纵向回流流速均满足规范要求，当取水口突然停止运营，取水口所在河汉内回流的最大流速为0．06m／s，对运河航段水流影响不明显；取水口运行时计算航段内水位最大差值约0．03m，对附近运河水域水位影响很小，对航道水深及往来行船安全无影响．

| Abstract: | Two-dimensional mathematical model is adopted to analyze the influence of Guanshu River Diversion Project on navigation. The results show that when the project is operated according to the design water flow, the maximum horizontal flow, the vertical impact velocity, the longitudinal flow velocity of the original channel can meet the requirements of regulations. When the water inlet suddenly stops operation, the maximum velocity of the water inlet is round 0.06 m/s, with limited effect on navigation. The maximum difference in the segment during intake runtime is about 0.03 m, which has little impact on water level, channel depth, as well as the navigating safety. |
