摘　　要：采用全站仪、数显百分表及精密水准仪在相同的观测条件下对桥梁挠度进行测量,以栾川县新双龙桥为例进行桥梁挠度观测试验,通过三种测量方法得到的试验数据进行对比分析,并用误差传播定律进行了精度分析,理论和实践均表明全站仪可满足挠度观测精度要求。在桥梁检测应用中,尤其是坡度和跨度比较大的情况下,该方法具有实际的参考价值。The total station,digital indicators and precise leveling instrument to measure the deflection of the bridge in the same observation conditions,the new Double Dragon Bridge Luanchuan County as an example for bridge deflection test,which the test data obtained by the three methods were analyzed,and the application of the error propagation law of precision analysis,which are theory and Practice show that the total station can meet the accuracy requirements.Deflection observation application in bridge detection,especially the relatively large slope and span,the method has practical reference value.
