Ltd. Beijing 100037 China; 3.Beijing Municipal Engineering Research Institute Beijing 100037 China) Abstract:Based on the experience accumulated and bined with the construction monitoring of a 88m main-span continuous girder bridge using hanging basket cantilever pouring method this paper discussed the mon problems occurred during the control calculation and proposed solutions for these problems. They include temporary rigid-connection simulation of the piles simulation of the actual construction conditions calculation and setting of the bridge pre-arch reference values for prestressed parameters k μ，etc.The theoretical analysis and field practice show that the calculation results matched the site monitoring very well and the main bridge jointed naturally.
