초록

To install heavy structures in the railway bridges, crane methods or launching methods using temporary structure have been applied. These methods are uneconomical because working yard is required, temporary cut of rail system, etc. In this study, various construction methods has been developed which are suitable to the filed conditions. In the case of simple span structure like plate girder bridges, the girder is loaded to troy system at the working yard and then transferred to the working place. To lift and lower the girder system, a new transfer system was developed. Different methods each for simple span bridge girder and long span girder were developed and detailed work procedures were proposed. Using these methods, the heavy structures can be installed with simple and safe work procedures and the construction cost and duration can be reduced.
