长江中游界牌河段已建航道整治工程效果分析
Effect analysis of regulation project of Jiepai reach in middle Yangtze River
摘要
Abstract
After the implementation of the waterway regulation project of Jiepai reach,the channel condition was improved obviously,and river flood was preliminary controlled.The dimensions of the channel,flow velocity,and flow state basically achieved the design standard.Due to the regulation project implementation time being late,after the implementation,shallow position was offset,river channel was broaden,and the mainstream in front of the fish-mouth project waved in large space.The navigable channel in shoal reach was not stable,which made the translocation between main flow and lateral branch in dry season.In the process of the conversion of the two branches,the channel in shoal reach of main branch was shallow and navigation-obstruction.Meanwhile,the Luoshan point bar was not controlled effectively,and the function of the fish-mouth project transformed from the defensive into deflecting flow pattern.关键词
