福姜沙水道深水航道整治思路及工程布置

Deepwater channel regulation ideas and project layout in Fujiang sand shoal channel

福姜沙河段目前呈三汊通航趋势,海轮航道走福南水道,江轮航道走福中水道,福北水道—如皋中汊为地方专用航道,目前三汊水深条件都不满足12.5 m深水航道要求尺度,为此必须进行整治。分析各汊道碍航情况及各汊道整治难度。针对各汊道碍航特性,提出整治原则及整治思路,在分析各汊道分流格局、水深条件、碍航特性等的基础上,提出整治工程平面布置形式。

There are three navigable channels in Fujiang sand shoal reach at present, i. e. Funan, Fuzhong and Fubei-Rugaozhong channel, which are the seagoing ship channel, riverboat channel and local special channel respectively. The three branch channels can＇ t meet the requirement of 12.5 m deepwater channel, therefore it is necessary to implement waterway regulation. This paper analyzes the navigation-obstruction situation and regulation difficulties of each branch channel. According to the navigation-obstruction features, the regulation principles and ideas are put forward. Based on the analysis results of the channel diversion pattern, depth conditions, and navigation-obstruction features, the regulation layout form is proposed.
