摘　　要：对于大多缺乏原始设计和施工资料的旧拱桥,很难对其承载能力作出准确的评定。以一座旧双曲拱桥的调查为例,提出了通过结构尺寸、拱轴线、截面配筋、材料强度和病害情况调查来恢复旧拱桥图纸的方法。该方法可以为缺失技术资料的旧拱桥的调查、检测提供参考。For most old arch bridges lack of original design and construction data,it is difficult to assess their bearing capacities accurately.Taking a double curvature arch bridge for example,a method of recovering design drawing was presented by measuring structural size and arch axis,and investigating reinforcing bar configuration,material strength and defect,which can provide references for field investigation of old arch bridges lack of technical data.
