摘要
Sediment research of TGP has been carried out for more than 40 years since 1958.This paper briefly describes the sediment research work of Yangtze River Scientific Research Institute in the reservoir area and damsite area of TGP in recent years.The research results demonstrate that sediment from Jinsha river and Jialing river reaches 83% of the total sediment at TGP.The completion of Xiluodu,Xiangjiaba and Tingzikou reservoirs will postpone the initial sediment balance time in TGP reservoir. In initial operation period of the project,the sediment in approach channels of the navigation structures can be cleared by machinery,in future period,the sediment outside the entrances of the upper and lower approach channels still need to be cleared by machinery while the sediment within the approach channel should be cleared by joint measures of flushing and mechanical dredging.
