Research on the bearing capacity of masonry arch bridge evaluation method

Aiming at the present situation in existing masonry arch bridges such as the deficiency of bearing capacity,diseases and so on,calculation theories and evaluation methods about the bearing capacity of masonry arch bridge were summarized in this paper.Simultaneously the comprehensive evaluation method which contains the appearance inspection,loading test,the calculation based on finite element analysis and relative assessment specification was proposed.On the basis of one large-span masonry arch bridge,the current situation of the bridge was analyzed and evaluated by comprehensive evaluation method,which was consistent with the facts.Engineering example shows that this method has good engineering practicability and theoretical significance.
