石拱桥填料能加强拱圈推力，分散石拱桥的集中载荷，减小结构的应力集中。不同填料对石拱桥受力性能的影响不同，合理把握填料参数对石拱桥的受力性能影响对石拱桥的设计和性能分析具有重要意义。建立某一石拱桥的有限元模型，利用Drucke‐Prager屈服准则，分析4种不同参数的典型填料对石拱桥受力性能的影响。结果表明，填料硬度对石拱桥在恒载和活载下拱圈的应力和挠度的影响不同。对十堰某一石拱桥进行荷载试验，试验结果与相应填料下的有限元模型分析结果较吻合，对比数据结果说明，为准确把握石拱桥的受力性能，应考虑填料参数的影响。

Fillers of the stone arch bridge can enhance arch thrusts ,scatter the concentrated load on stone arch and reduce structural stress concentration .Different fillers have different influences on the performance of a stone arch bridge ,and a good understanding of filler parameters to the performance of a stone arch stone is important to arch bridge design and performance analysis .Building a stone arch bridge finite element model ,using Drucke‐Prager yield criterion ,the paper analyzed the influences of four typical fillers with different parameters on the stone arch bridge .The analysis showed different fillers have different effects on the influence of the deflection and stress of the arch ring w hen under dead load and live load .A load test result of on a stone arch bridge in Shiyan is corresponding with the analytical result from finite element model test ,in order to accurately understand the mechanical prop‐erties of a stone arch bridge ,attention should be paied to the effects of the filler parameters .
