Construction of Beam Supporting System of Cast-in-situ Continuous Beam in Railway Passenger Line

The cast-in-situ continuous box girder beam is a key part of girder installation of prefabricated beams in the whole line.Combined with the construction example of cast-in-situ continuous box girder beam in one railway passenger line,the technique program of cast-in-situ continuous box girder beam bracket system was determined,the points for attention in construction were provided.It is vital how to reasonably select and put to use the bracket system of the cast-in-situ continuous box girder beam according to various construction situations.
