摘　　要：以重庆地区清.陆安桥为例,对石拱桥力学性能进行了非线性有限元分析,探讨了基于空间协同作用原理的石拱桥的受力机理。分析表明,拱墙和拱背填料对于石拱桥结构的侧向稳定、集中荷载的分散传递等均有重要的作用,有益于石拱桥的结构病害分析和加固保护。A case study of Chongqing·Lu＇an bridge,the mechanical property of stone arch bridge was carried out by nonlinear finite element analysis and stress mechanism of bridge based on the spatial synergistic effect principle was investigated.It is showed that the arch wall and arch back filler play an important role in lateral stability,dispersal transmission of concentrated load of stone arch bridge structure and disease analysis and reinforced protection.

关 键 词：石拱桥 接触非线性 空间协同作用
