Research On Optimization Of Route In YinGongZhou Channel After Opening 12.5-Meter Deep Water Channel

The Yangtze River is the busiest river in the world.Yangtze River below Nanjing 12.5 meters deep waterway construction project is the implementation of the national “The Belt and Road” strategy,the construction of key projects to build the Yangtze River economic belt,the Yangtze River golden waterway.The Deepwater Channel from Taicang to Nanjing is 280 kilometers.The second phase of the project to the Yangtze River Nantong to Nanjing River to implement key projects or waterway management projects,combined with dredging maintenance measures,the initial realization of Nanjing below 12.5 meters deep water channel construction goals.With the opening of 12.5m deep water channel,channel water depth conditions and other basic conditions to improve and change the channel,the Yangtze River in Nanjing,the following navigable situation will also be a major change.Into the river ship large-scale increase in the requirements of the channel,especially YinGongzhou channel,due to narrow channel,high traffic density,to the sea boat navigation has brought great difficulties.12.5m deep water channel opened,the Yangtze River downstream of the famous "tiger mouth" navigation security problems need to be resolved.In this paper,we focus on the route optimization of YinGongzhou channel after the opening of 12.5 meters deep water channel,and design three schemes to optimize these schemes from the perspective of ship capacity of YinGongzhou channel.And provide reference for the future route of YinGongzhou channel.First of all,the analysis of 12.5 meters deep waterway after the opening of YinGongzhou channel navigation status and predict the situation of navigable ship navigation.On the one hand,the YinGongzhou channel of a large number of research and analysis,clear YinGongzhou channel of the natural environment,waterway status,the status of the ship route navigation and traffic environment status.In this paper,the characteristics of traffic flow in YinGongzhou channel are analyzed emphatically,and the data of YinGongzhou channel ship are distributed by statistic method,ship velocity distribution,ship scale statistical distribution and ship track distribution.On the other hand,according to the future transport pattern and the latest identified navigation standards,to predict the future YinGongzhou channel of navigable ship and ship flow.Secondly,the route optimization scheme of YinGongzhou channel is studied.This paper proposes the use of simulation software Arena to study the research ability of YinGongzhou section capacity,combined with YinGongzhou channel traffic flow data to establish the existing one-way control section capacity simulation model of YinGongzhou channel and use simulation results to analyze the left branch of YinGongzhou channel.Based on the navigation status of Yin Gongzhou,the design scheme of three YinGongzhou channel is designed,and the three route schemes are discussed from the aspects of river adaptability,adaptability of port development,adaptability of ecological environment,adaptability and economy of navigation organization Comprehensive comparison.Finally,the three schemes are optimized from the perspective of ship's capacity.This paper uses the Arena simulation software to research the ship 's passing capacity of YinGongzhou channel,and selects the optimal and feasible scheme to provide the guarantee for the navigation safety of the ship.
