Analysis of UHPC Reinforcement Scheme for Masonry Arch Bridges
In view of the cracking of masonry arch bridge,on the basis of introducing the calculation design theory of masonry arch ring,combining with the actual operation of masonry arch bridge,this paper analyzes the cracking reason of masonry arch ring by using fracture mechanics theory,and puts forward the reinforcement scheme of strengthening masonry arch bridge with UHPC.Through the application of Hongyan Bridge,the results show that all sections can meet the requirements of normal service limit and ultimate state of bearing capacity after using the proposed scheme.
