Research On Safety Navigation Support Technology In Bridge Area

The growth of the national economy has led to the construction of the cross river bridge in our country,which has a positive impact on the surrounding economy and development.The cross river bridge has also changed the navigation environment of the bridge area.The number of ships are increasing rapidly,and the difficulty of bridge management is increasing.Accidents occur frequently in the bridge area,causing serious economic losses and casualties.In order to ensure the safe navigation of the ship,the main factors affecting the navigation of the ship are obtained through the statistical analysis of traffic accidents and the case analysis:According to the ship and human factors,by analyzing the shortcomings of the current quality of the crew and ship safety management,put forward to increase the ship safety inspection efforts,improve crew service quality,improve the seaworthiness of ship.In view of the environmental factors,considering the dynamic factors that affect the width of the channel,design scheme of the optimal layout of the waterway in the bridge area.The design of the channel width of the bridge area takes into account the influence of the wind drift and the drift of the ship,and at the same time,the buoys and channels in the bridge area should be arranged outside the turbulent vortex region.In view of the safety management in the bridge area,it is suggested that the VTS supervision should be strengthened,and the navigation aids,navigation aids and warning areas should be set up properly.The research in this paper is still insufficient to ensure the safety measures in the bridge area,and the follow-up can be further studied around the channel,supervision and management.
