In recent years, there have been varying degrees of hyperbolic arch diseases , a direct threat to the safe use of roads and bridges . How reasonable assessment of these in-service capacity hyperbolic arch , made safe, reliable, economical and practical reinforcement scheme , and thus on the hyperbolic arch reinforced for capacity , security reserves, and other research , for the active bridge repair, reinforcement and transformation has theoretical and practical significance. In this paper, the finite element software planar truss bridge full house finite element method calculation of internal forces seized the main arch reinforced three-dimensional solid elements and hanging around in the vapor -20 -100 simulate the response of the action , and on this basis for various parts of the reinforcement design . Before and after the bridge on the reinforcement static load simulation shows the reliability of calculations and reinforcement reinforcement feasibility . For full house hyperbolic arch , arch from epoxy mortar bonded steel reinforcement method selection , bonded steel construction process and considerations for capacity assessment study concluded , achieved the desired effect of strengthening put out , with some promotion practical value, can be extended to the fasting -plate arch bridge .
