Multimodal transport is the development trend of modern logistics,the key of which is the ability matching and smooth connection between different transport modes.Wharf is the interactive point of sea transportation and land transportation，so some wharves introduce railway into wharf to carry out multimodal transport,but the disconnection of railway to road transportation causes new problems.The traffic chaos,the conflict between container truck flow and the municipal traffic flow in harbor are the problems to be solved urgently in many wharves.The development of air-rail system provides new ideas and methods for solving these problems.Based on the development status of the air-rail system and the container supply structure and business demand of Qingdao port Qianwan port area,this paper studies the application of the air-rail system in the wharf from the practical level,analyzes the difficulties and solutions of the combination of the air-rail system and the wharf business,and provides reference for the wharf to adopt the air-rail system.To solve the problem of intermodal transport connection and port surface traffic congestion,air-rail is also a technical solution for other terminals.
