摘要
介绍了全站仪Z坐标测量在大断面隧道拱顶下沉量测中应用的原理和方法,与传统的接触式量测相比,全站仪Z坐标测量具有任意点设站、仅整平不需对中、免量仪器高等优点,极大地提高了现场的工作效率,对类似工程具有参考意义。
The principle and method of non-contact arch settlement measurement to large cross-section tunnel of z coordinate survey by total station are described in this article. Compared the traditional method,it has the advantages of free location, non-prism, not centering but circle settling screw, no height of the instrument and prism and so on. This method improves the efficiency greatly in tunnel arch settlement measurement survey, which has reference significance for similar engineering.
