摘　　要：钢结构的异常变形或局部损坏可通过荷载—挠度曲线以及纵轴线的挠度曲线反映出来。利用数字摄影测量方法进行钢结构的变形监测是传统测量方式的变革 ,可实现半自动的实时监测。The abnormal deformation or local damage of steel structure can be reflected by the load-deflection curve and the deflection curve of the longitudinal axis.Using the digital photogrammetr survering method to do the deformation monitoring of steel structure is a revolution of the traditional surveying mode.It can realize the semi-automatic method of the real-time monitoring. The paper introduces the corresponding surveying method and gives the experimental result.
