在对地下空间进行控制测量时,导线检测是一种常用的手段,但是如果底下的导线过长,导线检测就会显现缺陷。此时我们可以选择陀螺全站仪,本篇文章以实际的工程为例,重点介绍了陀螺全站仪的工作过程,并且提出了在加测多个方位角时所需要考虑的因素,而且将未经陀螺全站仪测量的方位角与加测后的结果相互对比,并且进行了详细的分析。 Wire inspection is a common practice when making controlled measurements of subsurface space, but wire inspection reveals defects if the underlying wire is too long. At this point we can choose the gyro total station, this article takes the actual project as an example, mainly introduces the working process of the gyro total station, and puts forward the factors that need to be considered when adding multiple azimuths, The azimuth measured without gyro total station is compared with the result after adding test, and a detailed analysis is carried out.
