Application of Large-Span Cast-in-Situ Prestressed Hollow Slab in Public Works
The top board of Nanping underground expressway is an arched board with the radius of 600 meters,which has a maximum span of 32.26 meters and a minimum span of 21.75 meters. By comparison of different slab types,large-span cast-in-situ prestressed hollow slab structure is selected. Based on this work,the paper introduced the technology,calculation method and construction measures of one-way prestressed hollow slab structure.
