摘要
采用全站仪和精密水准仪同条件观测桥梁挠度，选定了相应的观测方法，通过精密水准仪观测数据检核全站仪观测成果，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可满足挠度观测精度要求。
The bridge deformation was measured by a total station instrument and a precise level instrument at the same condition.The surveying data were compared and analyzed by the principle of error.The results show that the total station instrument can meet the accurate of bridge deformation surveying.
