用悬高测量法进行拱轴线检测

对于拱桥,确定拱轴线形是拱桥检测评估和维修加固的基础工作。本文以景观桥为例,对利用全站仪悬高测量原理测量测定拱轴线形的方法进行了探讨。结果表明该方法具有操作简单,方便快捷,精度高,拱圈线形测量效果较好,特别适合对无预置观测点的旧桥线型观测。

Arch Axis Detection by Using Hanging High Measurement

For arch bridge, determine the arch assessment, maintenance, and reinforcemenL This axis shape is the foundation work of arch bridge detection article takes the landscape bridge as an example; the use of total station hanging high measuring principle measuring measurement arch axis shape has been discussed. The results show that the method has simple operation, convenient and quick, accuracy; high arch ring line measurement effect is good, especially suitable for no preset observation point of certain old linear observation.
