Research on Integral Lifting Continuous Steel Box Girder Bridge Construction Technology
Due to over length and weight of the girder segment, the main bridge steel box girder of Chongqi Bridge adopts large segment integral lifting erection method; two sets of large floating cranes are needed for hoisting. According to the water environment condition at site, select the lifting equipments to research on; conduct restrict checking on the lifting weight, height and amplitude; new automatic balance type lifting sling structure form is adopted during lifting erection to make sure the stress on each lifting point is balanced; conduct optimization design onto the lifting points; aimed at lifting erection of large segments, use ansys to establish large solid simulation model for finite element analysis so as to guarantee safety of steel box girder structure during lifting erection of large segment.
