摘要
以免棱镜全站仪为测量设备,利用测点高差相减法对地下隧道拱顶的沉降变形量进行了测量。测量结果表明:该方法能够精确地测量地下隧道拱顶的沉降变形量,且具有操作简单、测量方便、计量准确的优点,可极大地提升隧道施工安全性和效率。
In order to avoid prism total station as measuring equipment, the settlement deformation of underground tunnel arch is measured by using the subtractive method of height difference of measuring point. The measurement results show that the method can accurately measure the settlement deformation of the arch roof of the underground tunnel, and has the advantages of simple operation, convenient measurement and accurate measurement, and can greatly improve the safety and efficiency of tunnel construction.
