摘要: 建立石拱桥有限元模型时,为使结果更接近实际受力情况,需考虑拱上建筑联合作用影响。以此为基础,提 出横向系杆法和等代拱法2 种方法改进计算模型,并在工程实例中论证2 种方法的可行性和有效性。为石拱桥的 承载力评估和加固等提供指导。

Abstract: In order to make the result closer to the actual stress,spandrel construction combined action was considered when the finite element model of stone arch bridge was established. On this basis,transverse tie bar method and equipollent arch method were offered to improve calculation model. Then the feasibility and effectiveness of the methods could be demonstrated in project cases. The conclusions could provide guidance for bearing capacity estimation and reinforcement of stone arch bridge.

Key words: stone arch bridge, spandrel structure combined action, transverse tie bar method, equipollent arch method
