External prestress multipoint anchoring strengthening method of bridge structure
The invention discloses an external prestress multipoint anchoring strengthening method of a bridge structure. After prestressed steel completes tensioning, anchoring of ends is performed firstly, and then elastic anchoring of midpoints is performed. Compared with a conventional anchoring method, the method solves defects in a conventional two-point-anchoring that effective prestress is too fast to loss when dynamic load is applied, and the method is an effective active strengthening method. The method is advantaged of realizing to ensure integrated effect after prestress tensioning, compensating loss of internal prestress, improving bearing capacity, closing cracks and controlling expansion of the cracks, properly restoring structural linetype and stopping midspan from downwarping continuously, and obviously changing force bearing performance of a concrete structure.
