Abstract

Abstract: From Jun. 2003 to Sep. 2006，the Three Ggorges Reservoir is running with the 135—139 m dispatching operation scheme． The scheme means the water level is 139m during low water season and 135m during flood season． The backwater end is located at Lidu in Fuling district，and the reach ever in back water is below Fengdu． Through analyzing the prototype observation data of the Three Gorges Reservoir，the variety characteristics and the gradation of sediment in this reach has been studied． The rule of sediment motion is obtained based on the analysis of sediment size in this reach，which could be a preliminary understanding of sediment motion rule in the Three Gorges Reservoir district．

Key words: the Three Gorges Reservoir, river bed sediment, deposit, sediment motion

摘要： 从2003 年6 月—2006 年9 月三峡水库库水位按135 ～ 139 m 方式运行( 枯水期坝前水位139 m，汛期坝前水位 135 m) ，其回水末端位于涪陵李渡附近，常年库区在丰都以下。分析了该阶段蓄水期三峡库区原型观测资料，研究了万州—涪陵李渡河段床沙沿程变化特性及淤积物的级配组成，由该河段的床沙粒径变化分析其泥沙基本运动规律，从而对该河段以至于三峡库区的泥沙运动规律有一个初步的认识。
