| 摘 要： | 桥梁结构的老化、车辆荷载的增加、不利环境的侵蚀、养护维修的缺乏等综合因素,使得桥梁结构不可避免地产生各种损伤,导致了桥梁承载力和耐久性的降低,从而过早地失效或丧失功能。结合实际工程背景,进行了病害调查、动静载试验及结构检算,对桥梁现有状况进行检测。结果表明：荷载试验结合理论分析的研究方法能够较好地得到既有钢管混凝土拱桥的承载能力评估结果,同时对今后同类型桥梁结构的维修加固具有一定的借鉴意义。

| Abstract: | Combining actual engineering , the paper carried on harm inquisition, load experiment and structure analysis to examine the existing condition of the bridge. The result indicated that the research method combining the load experiment with theory analysis can easily obtain the bearing capacity appraisal result of the existing steel tube concrete arched bridges, which may supply references to the maintenance and reinforcement of the same type of bridges. |
