Abstract: Firstly，the shortages of existing specifications in evaluating the checking coefficient of spandrel-filled arch bridges were analyzed，and the disease forms and distribution rules were summed up，with the combination of several case studies of reinforcing spandrel-filled arch bridges． The major influential factors of the checking coefficient in existing bridges were determined by analytic hierarchy process，which included the abutment displacement，diseases of the main arch ring and deviation of the arch axis． The secondary fuzzy synthetic evaluation method of the checking coefficient was established according to the fuzzy mathematical theory． Therefore，a fast method to calculate the checking coefficient was proposed on the basis of the appearance investigation of spandrel-filled arch bridges． Lastly，the VB language was adopted to program and visualize the proposed fast calculation method，in order to promote this method in engineering practice．

Key words: spandrel-filled arch bridge, checking coefficient, analytic hierarchy process, the secondary fuzzy synthetic evaluation
