　　For large span steel tied bars basket-style arch bridge, the structural system is very complex and the construction process system conversion is frequently.For the reason of bridge line type and stress can meet the design requirements real-time control is necessary in the process of construction This article take a particular arch bridge as the research object, calculate accurately line type (line type of suspension bridge; alignment line type; preassembly line type) of the steel box arch and steel box girder.Contacting the specific construction methods, reveal internal transformation of the relationship between the three line type and the correlation of a variety of line type and construction methods.
