| Abstract: | Combing the advantages of the methods of strengthening reinforced concrete bridges with external prestressing and (steel-plate) gluing, a new method of strengthening is put forward--"prestressed (steel-plate) gluing". The process of construction is investigated by experiments. The results of experiments prove that the new method of strengthening is feasible and it can notably improve the rigidity and bearing capacity of a reinforced concrete bridge in the normal use stage. Finally, points of attention are given as to applying this new method of strengthening to a real bridge. |
