摘　　要：针对目前既有诸多圬工拱桥出现承载能力不足及病害等问题,总结了圬工拱桥承载能力的计算理论和评估方法,提出了外观检测、荷载试验,并根据有限元计算结果,结合相关评估规范等多种评定方法相结合的综合分析评定方法。以某大跨圬工拱桥为例,应用综合分析评定方法评定该桥现有状况,与实际情况较为吻合,表明该方法具有较好的工程实用使用价值和理论意义。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.
