Abstract：Research purposes: The relevant technique about railway ferry in early years is not adopt to the modern development and the need of the traffic in our country. As the motorcycle，vehicle，turnout and relevant technique condition between the foreign country and our country are different deeply，the things in foreign country can not be adopted in the design and construction of Yantai-Dalian railway ferry. Therefore，it is necessary for us to systematically study the relevant questions adopting to the engineering characteristics of Yantai-Dalian railway ferry，and the research provides theoretical basis for the guide on railway berry technique design，norm design method，construction and operation.
Research methods: This paper investigates the relevent questions about the railway ferry adopting to the motorcycle， vehicle and work characteristic，with computer check of illustrated manual table，theoretical analysis，calculation and imitation experiment. And we get a right conclusion through scientific research.
Research conclusions: The questions，which involved in the engineering，such as station shape，work method，ability calculation，the max slope of trestle and trestle orbit } have been solved. Especially，the railway trestle absorbs many advanced techniques，being rated as“four first" of railway ferry in our country. The research and design results of Yantai-Dalian railway ferry have passed the reviewing of the supervisor section in our country. Many have been carried on in the engineering construction，and the parts of results have been adopted in “Railway industry station，harbour station design norm" and ”The railway station and terminal design technique manual"
