一种提高对边测量隧道拱顶下沉精度的方法
摘要：
本发明涉及一种提高隧道拱顶下沉量测精度的方法，具体涉及一种提高对边测量隧道拱顶下沉精度的方法。其采用全站仪对边量测法，基于现场隧道拱顶下沉量测实际情况，通过选择合理的后视点及全站仪布设位置，提高测量精度。本发明采用的方法步骤为：首先，将监测点埋设在监测断面拱顶位置，并进行保护，避免监测点在隧道施工中被影响破坏；其次，选择合理位置埋设后视基准点：然后，根据埋设的后视基准点与监测点之间的水平距离，选择全站仪的架设位置；最后，利用全站仪对边测量功能完成量测数据读取，并在每一次量测完成后恢复监测点与后视点的保护。
摘要（英）：

The invention relates to a method for improving the measurement precision of the settlement amount of a tunnel vault, in particular to a method for improving the precision of opposite side measurement for the settlement of the tunnel vault. According to the method, a total station opposite side measuring method is adopted, and the measuring precision is improved by selecting a reasonable rearview point and a total station arrangement position based on the practical measurement situation of the amount of field tunnel vault settlement. The method comprises the steps that firstly, a monitoring point is embedded in the vault position of a monitoring section and is protected so as to prevent the monitoring point from being influenced and damaged in tunnel construction; secondly, a reasonable position is selected to embed a rearview reference point; thirdly, the erecting position of a total station is selected according to the horizontal distance between the embedded rearview reference point and the monitoring point; finally, measuring data are read through the opposite side measuring function of the total station, and protection on the monitoring point and the rearview point is restored after every time measurement is completed.
