The Reinforcement Design and Calculation Analysis of Large-span Two-way Curved Arch Bridge
At present,the structural defects and diseases of two-way curved arch bridge are gradually emerging,and it is urgent to reinforce and reconstruct this type of bridge.The reinforcement design of a large-span two-way curved arch bridge is studied.By investigating the existing diseases of the bridge and conducting finite element calculation analysis before and after reinforcement,the final reinforcement design scheme is determined.The results show that the large-span two-way curved arch bridge adopts the reinforcement design scheme of increasing the interface of the main arch ring,reducing the persistent load of the bridge deck system and enhancing the lateral connection,which can effectively improve the structural stress of the two-way curved arch bridge and improve the bearing capacity and overall stability.The design scheme can provide a useful reference for the later reinforcement of similar bridge types.
