摘　　要：桥梁轴线线形测定是桥梁承载力评定、病害分析、健康状态分析及竣工验收的重要环节.结合依托工程,以拱桥主拱线形测定为例,介绍了“两面角法”测量桥梁轴线线形技术.实践证明,该项技术具有简便易行、精度高等特点,工程应用价值较高.The bridge axial alignment is a key point to bridge bearing capacity evaluation, disease analysis,health analysis and taklng-over inspection. However, the routine technique is costly both in time and in finance, and what＇s more, the preciseness of the inspection can＇t be guaranteed. Taking the main arch axial alignment of an existing arch bridge as an example, the dihedral method in measuring bridge axial alignment is introduced. The experiment proves that the discussed technique is reliable, precise, simple and practical.
