Research and Evaluation on the Bearing Capacity of an Open-web Catenary Masonry Arch Bridge
An open-web catenary masonry arch bridge has been built for a long time,and the design data are missing.In this paper,through the field measurement of structural size parameters,stone strength and other data,combined with the design load parameters of bridges in similar years and the current traffic load of bridges,on the basis of com-munication with the management and maintenance units,through the on-site bridge appearance inspection and load test,the bridge bearing capacity is checked and calcu-lated to determine the appropriate bridge load level.The research results can provide some reference for the main-tenance and bearing capacity evaluation of similar bridges with long history and missing data.
