To provide technical basis for assembly steel girder in incremental launching method, aimed at the problem of assembling steel girder leaded erection line change which is influenced by temperature variation. According to the vertical temperature variation of steel girder measures in situation in this paper, temperature gradient model was fitted, and the influence of angle for assembly steel girder end under different temperature gradient model was investigated. The results show that angle of assembly steel girder end caused by temperature gradient of top and bottom plane was remarkable. Different assembly temperature scope for top and bottom plane of steel girder was suitable to different segments.
