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

摘要： 在分析现有规范对实腹式拱桥承载能力检算系数评定方法不足的基础上，结合课题组多个实腹式拱桥加固实 例总结其病害形式及分布规律，采用层次分析法确定旧桥检算系数主要影响因素为桥台位移、主拱圈病害、拱轴线 偏离，利用模糊数学原理构造检算系数的二级模糊综合评估方法，建立基于外观调查的实腹式拱桥检算系数快速计 算方法。并利用VisualBasic可视化编程语言将该检算系数快速计算方法实现程序化、可视化，便于在工程实践中 推广应用。
