| Abstract: | Based on the information of integral steel side formwork of the continuous box-girder in the Qingdao bay-bridge construction,liquid side pressure during layer pouring is computed in this paper,the most adverse influences on steel side formwork produced by liquid side pressure are calculated from three time-points according to the concrete initial-setting time,and stability analysis of the steel side formwork is accomplished.It provides important reference for design and computation of full-scale supports. |
