In view of the lack of navigation capacity of the upstream channel opening of Nanjing Yangtze River Bridge,it is necessary to improve the navigation environment and guarantee the safe operation of the bridge and ship by making full use of the bridge navigable bridge opening and increasing the navigable upstream opening hole.According to the natural channel conditions of the Nanjing Yangtze River Bridge section,and based on the bed evolution and flow conditions in different years,we propose the scheme and probe into the feasibility of opening the bridge upstream channel at the 5th opening hole.The results show that the 5th hole of the Nanjing Yangtze River Bridge has the same span as the current navigable hole,and the bridge section is characterized by the deep and wide channel,so it bears the basic condition for opening the navigable hole.It is suggested to just open the 5th hole as the upstream navigable hole,and in the future it can be adjusted according to the vessel traffic situation.
