摘　　要：随着经济发展、交通日益繁重和桥梁服役时间延长,对桥梁进行检测是十分有意义和必要的。但是在面对一些特殊桥梁,如:跨河、跨铁路、跨山涧等,传统方法测量桥梁的挠度是有一定困难的。利用全站仪提供的悬高测量法则可以方便快捷的进行测量。通过误差分析和试验以及实桥验证,表明悬高测量方法具有较强的操作性和较高的可信度。With economic development, trafifc is becoming more and more busy and Bridges use extend service time, so test the bridge is very meaningful and necessary. But in the face of some special Bridges, such as：across a river, across the railway, across a mountain stream, etc.,it is dififcult to measure bridges by traditional ways. Using total station device by high measurement method can be measured conveniently. The error analysis and test, and actual bridge test show that suspended high measuring method has strong operability and high credibility.
