摘　　要：通过调查归纳出三峡库区石拱桥典型病害,借助空间有限元软件对4类典型病害进行了分析研究。在此基础上得出了基于4类典型病害的桥梁安全性限值指标及鉴定技术,对基层工程技术人员有效方便的评估石拱桥安全性起到一定的借鉴作用。The typical diseases of stone arch bridge in the Three Gorges Reservoir area are summarized through the investigation, and four kinds of typical diseases of stone arch bridges are investigated and evaluated by spatial finite element software. Based on these investigations, the limited value index of the security and the identification technology of the four typical diseases of the bridge are obtained, which is of certain referential significance for the rank-and-file technical personnel to evaluate the security of stone arch bridge effectively and expediently.
