Construction Technique Control of Supporting Platform Applying Bottom Template for Cast-in-Situ Large-span Girders on Sea

The paper gives an emphasized presentation of construction technology control of supporting platform applying bottom template carried out in cast-in-situ girders construction of the approach bridge for 70000 dwt specialized coal-unloading terminal of Qinzhou Coal-fired Power Station.By adopting the design scheme of bracket,main girder and hypo-girder and bottom template's demoulding technique,the difficulties in in-situ casting of large-span girders are solved.
