Numerical Analysis Reinforcement And Increasing Load For Mantanghong Bridge

Recently, a direct threat to the safe use of roads and bridges because of different degrees'disease of double arched bridge. It will be most significance in theory and in practical how to assess reasonably to the bearing capacity of these existing double-arched bridge and made a safe, reliable, practical and economic reinforcement, further more research on load-carrying capacity and security reserves of these existing and reinforced double-arched bridge.It has used plane finite element method of finite element software for calculating internal forces for bridge in Mantanghong, the main arch of the three-dimensional entity in the reinforcing and reinforced double-arched bridge in the car-20 and trailer-100 rank has been simulated. According to that so it has designed the reinforcement and assess to each part of the reinforcement .Before and after the arch bridge on the reinforcement of the static load simulation, illustrates the consolidation and strengthening the reliability of the calculation scheme is feasible.Against double-arched bridges for Mantanghong , take advantage of the method Epoxy resin mortar to reinforce paste steel plate on arch ribs,and the process of Paste steel plate and its notes , its attention and research on load-carrying capacity. It achieve the desired effect of reinforcing to mention set,so it has some practical value to promote,Can be extended to fasting-plate arch arch bridge.
