三峡工程运用初期上荆江杨家脑至郝穴河床冲淤变化试验研究

三峡水库修建后,由于水库调蓄作用,进入坝下游荆江河道的水沙过程发生了显著变化,荆江河道产生较明显的冲刷,已引起局部河段的河势调整,将在相当长时期内对两岸堤防、已建护岸工程和河道整治工程及河道的稳定产生不同程度影响,进而影响该地区的防洪、航运、生态与环境以及河流的综合服务功能的正常发挥.利用长江防洪实体动床模型试验研究了...

Physical Modeling of Morphological Changes in Upper Jingjiang River Course from Yangjianao to Haoxue at Initial Operation Stage of Three Gorges Project

Due to the reservoir regulation of the Three Gorges Project(TGP),the water and sediment load flowing into the Jingjiang river reach downstream of,TGP have undergone significant changes both in the process and in the amount.Conspicuous erosion,which leads to river regime changes in some locations,has occurred in the Jingjiang river channel,consequently affecting the embankments,bank protection works along both sides,river regulation projects,and the stability of river bed at different levels in the long-run,...
