Abstract: There are many stone arch bridges in our country, in the long time of operation, there are some dis-eases in the stone arch bridges. They seriously affect the normal use and capacity of the bridge and the service life of the bridge. Therefore, it is necessary to carry out maintenance and reinforcement and reconstruction to improve the ｌｏａｄ level. This paper research the several stone arch bridge upper structure reinforcement tech-nology, analysis of the reinforcement mechanism of arch bridge, the characteristics and the applicable range of, and of these reinforcement technology were compared and analysis to on the basis of better use them for stone arch bridge reinforcement.
