Method for applying external prestress to assembled slab bridge
The invention relates to the technical field of highway bridge construction and maintenance, in particular to a method for applying external prestress to an assembled slab bridge. The method is wide in application, can be used for upgrading and rebuilding of newly-built bridges and existing bridges and solidification of old bridges, and can also be used for other bridge types. According to the method, external prestress is flexible to apply, can be applied to partial slab bridge or even a block of slab bridge, and can also be applied to a full-span bridge; the method can be used as a temporary solidifying means when an overweight vehicle passes the bridge, and can also be used as a permanent measure for improving bridge loading class; the method can not only be applied to a prestressed concrete slab bridge, but also be applied to a reinforced concrete slab bridge; and by applying external prestress to the assembled slab bridge, the loading capacity of the assembled slab bridge can be improved, and the service life of the slab bridge can be prolonged.
