摘　　要：襄樊电厂一、二期工程均以汉江为水源,采用直流供水方式,排水入汉江。本文建立了电厂取、排水口河段动床实体模型,考虑了在建的南水北调工程和拟建的崔家营航电工程对该河段的河床演变和水流泥沙运动影响,从三维空间角度详细研究了取、排水河段水流泥沙运动及河道冲淤演变趋势、取水口附近底沙运动情况、取水安全可靠性等问题,并提出了稳定取、排水口附近河岸及保证取水可靠的建议性措施。The first and second stage of Xiangfan power plant is designed to take water from Hanjiang River and drain the cooling water into the same River. The physical model for the intake and outlet reach has been built in this paper. At the same time, the influence of South-North Water Transfer Project and Cuijiaying hydroelectric project on the riverbed deformation and flow-sediment movement are investigated. Finally, some suggestions are given to stabilize bank near the intake and outlet reach and to assure the safe water taking.
