Solutions to Deviation in Closure Site of Long-Span Cable-Stayed Bridge

Taking a cable-stayed bridge in Boffa Province, Guinea as an example, the shortness of the link section encountered during the closure process on the construction site was analyzed. Based on the unstressed state method, the finite element software was used for simulation calculation, and combined with the actual measured data on site, the closure plan was contrapuntally drawn up. The calculated and measured results show that selecting the non-low temperature period for direct linking with the existing section has little effect on the closured state of the cable-stayed bridge. This solution ensures that the bridge can be safely closured, and which provides a certain reference for the treatment of similar problems encountered in construction process of other large-span cable-stayed bridges.
