| Abstract: | Aiming at no bonding pre-stress concrete cored slab bridge,this paper utilizes finite element software for numerical simulation,compares and analyzes the minimal cutting depth of ring openings,square openings and translots of different dimensions as the stress release of surface concrete is up to zero,providing the reference for existing prestress detection of such bridges. |
