Abstract:In view of the complicated navigation environment in Yingongzhou channel, limited channel capacity and frequent ship accidents, we use the data analysis method to analyze the influence of ship traffic flow characteristics and hydrology-weather conditions, and point out the key problems faced by Yingongzhou channel.Based on the analysis of the historical evolution and field investigation of the southern branch channel of Jiaobei waterfront, we propose the idea and planning of constructing the southern branch of Jiaobei waterfront into the Grade 3 channel of the inland river, as well as the technical engineering measures to be taken. By analyzing the influence of the opening of new channel on the navigation environment in Yingongzhou channel, we draw the conclusion that the opening of the southern branch channel of Jiaobei waterfront can improve the navigation conditions, enhance the passing capacity and reduce the safety risk of Yingongzhou channel.Furthermore, we carry out an analysis on the benefits of safety, economy and environmental protection and other advantages, and propose suggestions to carry out more in-depth study for the opening of the southern branch channel of Jiaobei waterfront.
