| Abstract: | On the basis of some common problems in the freely supported hollow slab bridge,such as the link strength in horizontal direction being not enough,the deflection of hollow slab being larger as single slab acted by force,the sensing of vibration in bridge floor being strong and etc.,the strengthening of bridge is realized by using prestressing without bond technique,which may be referenced for the strengthening of same kinds of bridges. |
