for application and populization of the corrugated steel web PC composite box-girder bridge, a new asynchronous cantilever construction method was proposed to reflect the social and economic benefits of this type bridge in short term. In this paper, comparisons of the construction process and economic indexes between the traditional hanging basket cantilever construction method and the asynchronous cantilever method. Combination of the large finite element program ANSYS, a fine finite element model of the studied bridge was built, some analysis of the bridge structure were conducted for the whole process of construction, the calculation results were compared with the field testing data by the real-time monitored stress and displacement. The results indicated that the process of asynchronous cantilever construction method is simple and clear, the construction period is short and the economic indicator is high. This proposed asynchronous cantilever construction method is far superior to the traditional hanging basket cantilever construction method. The deformation and stress of structure were varied in a reasonable and safety range during the construction for the proposed method. The structural stress distribution of the proposed method is more reasonable than that of the traditional hanging basket cantilever construction method.
