Optimization Model of the Inland Bridge Navigation Hole

In order to make full use of the river coast resources and reduce the influence of the inland bridge construction on the shipping and logistics distribution, this paper uses the method combining the dynamic programming and grey theory to establish inland river bridge navigation hole distribution optimization model. Using the Wuhan Zhuankou bridge as an example, according to the Wuhan section of the Yangtze River in 2014 water level value and he bridge area of the underwater terrain features, the model has been verified.
