Abstract: Based on the field data of the Three Gorges Reservoir from 2003 to 2006,the sedimentation deposition in the Yangtze River from Wanzhou to Fuling during 135-139m operational phase is analyzed. It is showed that there are 20 reaches sediment deposited and 3 reaches scoured. The total sedimentation in the Yangtze River between Wanzhou and Fuling is about 1. 56 billion m3 and about 1. 5 billion m3 sands ( 96. 2% of the total sedimentation) ,which is deposited downstream of Fengdu. The places,such as continuous curve bend,broad reach,and so on,are mostly deposited areas. With the operational time of the Three Gorges Reservoir,the gradation composition of sedimentation gradually becomes fine. In future while storage level is rising furthermore,sedimentation in continuous curve bend will increase greatly,which will obstruct navigation

Key words: the Yangtze River, river reach from Wanzhou to Fuling, sedimentation

摘要: 利用三峡水库2003—2006 年间的实测资料分析了135-139 m 蓄水阶段万州—涪陵河段的泥沙淤积特 性。结果表明: 该河段内共有20 处泥沙淤积,3 处冲刷,淤积总量约为1. 6 亿m3 ,冲刷总量约为0. 04 亿m3 , 净淤积总量约1. 56 亿m3 ; 丰都以下的河段发生淤积共计17 处,泥沙净淤积量约为1. 50 亿m3 ,约占总淤积 量的96. 2% ; 河段内泥沙重点淤积在连续弯曲、宽谷等类型的河段; 随着水库蓄水年限的增加,泥沙淤积物级 配组成呈逐年变细的趋势。长期来看,随着水库运行水位的进一步抬高,连续弯曲河段的泥沙淤积将进一步 加重,将影响航道通航。
