摘　　要：针对引江补汉工程实施后丹江口—黄家港断面最小通航流量减少而引起水位下降的问题,进行了汉江丹江口—黄家港河段的综合整治工程研究。采用平面二维水流数学模型对工程河段综合整治工程实施前后的航道通航水流条件进行模拟对比分析。结果表明,实施综合整治工程可有效改善通航水流条件,解决了因最小通航流量减少、水位下降导致局部河段通航标准降低的难题,可为南水北调引江补汉工程实施提供技术支撑。In view of the decrease of water level caused by the decrease of minimum navigable flow at the Danjiangkou to Huangjiagang section after the implementation of the Yangtze River Diversion Project and Hanjiang River Reinforcement Project,the comprehensive regulation project of Danjiangkou to Huangjiagang section of Hanjiang River is studied.A two-dimensional flow mathematical model is used to simulate and compare the navigation flow conditions of the waterway before and after the implementation of the comprehensive regulation project.The results show that the implementation of comprehensive regulation project can effectively improve the navigation water flow conditions,solve the problem of reducing navigation standards in local river sections due to the reduction of minimum navigation flow and water level,and provide technical support for the implementation of the South-to-North Water Diversion Project.
