摘　　要：基于我国大量石拱桥修建历史久远且交通运营需求不断提高的现状,亟须对这些老石拱桥的承载能力和健康状况进行准确的评价。以某石拱桥为例,利用Midas软件建立有限元分析模型,对其结构承载能力进行验算,并按照现行规范进行荷载试验,以及相应的分析,为桥梁养护部门做出合理的决策提供依据。A large number of stone arch bridges in our country have a long construction history and the transport operators demand is increasing.It is imperative to make accurate assessment on the bearing capacity and health situation of the old stone arch bridges.Combining with a project of stone arch bridge,we used the finite element software Midas to establish the finite element analytical model and made structure checking on bearing capacity.In addition,we conducted load test and analysis according to the existing norms,which could provide the basis for bridge maintenance department to make reasonable decisions.
