长江下游安庆水道河床演变和航道整治思路
Riverbed evolution and waterway regulation ideas of Anqing Waterway in the lower Yangtze River
摘要
Abstract
A comparative analysis of riverbed evolution before and after the impoundment of TGP was carried out in this paper.The results show that the sand beach and bank in Anqing Waterway have a characteristic of periodic changes under natural conditions, and the riverbed and navigation conditions of branches change rapidly.After the impoundment of TGP,the evolution rules remain unchanged,and the navigation condition of the entrance region of left branch will expand towards adverse direction under the tendency of development of Xinzhou sandbar to the right.After the implementation of the river pattern control project,the boundary condition of the new middle branch is changed,and the periodic evolution process becomes slower,which is beneficial to maintaining the current branches pattern.On the basis of summarizing the characteristic of navigation obstruction of Anqing reach,the regulation ideas of limiting the middle branch development,adjusting distributary of branches, stabilizing river beach and scouring the channel by flow contraction for Anqing Waterway were presented in this paper.关键词
