摘要
采用精度较高的全站仪,选定相应的观测方法,以广和大桥为例进行桥梁挠度观测试验,由得到的试验数据进行对比分析,并应用误差传播定律进行精度分析,理论和实践均证明全站仪在一定的条件下能代替精密水准仪进行挠度检测。
With a high-precision total station theodolite,a homologous measure method is provided to take a great deal of experiments about the detection of guanghe bridge deflection.With the law of propagation of errors to dissect the surveying data,the results show that the high-precision level can be taken the place of the total station theodolite to detect bridge de-flection under certain conditions.
