(China Construction Fifth Engineering Bureau Co.,Ltd.,Changsha ,Hu nan ㊀410004,China )Abstract :The basement side of Changsha ice and snow world project is built near a hundred meter deep excavation,and the bottom plate is nearly 1/3of the area suspended,which is a stilted building structure,with the maximum suspended height of nearly 30m.The superstructure is partially cantilevered,with the maximum cantilevered length of nearly 9m.The karst cave in the deep excavation is developed with uneven terrain.The traditional steel pipe scaffold is used to set up the formwork system,which has great potential safety hazard.In view of the difficulties of the project,using the advantages of high bearing capacity and large span of Bailey frame,flexible combination of use,crossing the cliff,forming a closed steel platform,and erecting steel pipe scaffold on it,safe and reliable.In this paper,the supporting scheme,the supporting system design and the cantilever end supporting system design are introduced in detail.Key words :excavation;stilted building structure;cantilever structure;Bailey truss;support formwork;construction
