四边交会法在桥梁变形监测中的应用

摘要

This paper proves the availability of monitoring the three-dimensional deformation of bridges using the method of 4-length of side inter section and condition abjustment,as well as it's unparalleled adventure comparing with other methods,throngh the case of monitoringthe Pearl River Bridge.It can eliminate the inconvenience of deform alion measuring cansed by hanging,shaking and spatial inaccessibility while saving the cost.%通过珠江大桥监测实践,证明四边交会条件平差方法进行桥梁精密三维变形监测是可行的,具有其他方法无可比拟的优势。四边交会法解决了桥梁变形监测因悬空、震动、测点难以到达而不便于测量的问题,而且节约成本。
