Abstract:The correlation of cracking moment  between prestressed hollow slabs and  laminated hollow slabs are analysed.  The calculation models and equations about the correlation are also suggested as reference for prestressed hollow slabs and laminated hollow slabs in design, production, construction and working out of general standard gallery.
Keywords:prestressed hollow slab； laminate hollow slab；  correlation in cracking moment
