摘　　要：三峡工程规模宏大,具有巨大的防洪、发电、航运等综合效益,是治理和开发长江的骨干工程。涉及面极广,影响深远,库尾段恰位于西南重镇重庆市,其水面线变化规律及其回水末端历来为人们所重视,正确了解其回水末端具有极其重要的战略意义。本文采用2004,2005年原型观测资料,研究了三峡水库围堰发电期135 m蓄水位时的库区沿程水位、水面线变化规律,初步确定了各流量级的回水末端位置。The magnificent Three Gorges Project is the key to treat and develop the Yangtze river,which has a great benefits such as flood control,power generation and shipping,etc.The project relate wide field and has a deep influence.The change regular of water surface profile and terminal of backwater are very important and to pay attention always,because the reservoir terminal located in Chongqing city,then to know the real terminal of backwater has the extremely important strategic significance.Based on the prototype observation data in 2004 and 2005 year,the paper studies the change regular of level and water surface profile along the way at 135m generation water level in period of construction for Three Gorges Reservoir,determines preliminarily the terminal position of backwater for different flows.
