快速测量法在隧道施工中的应用

测量工作伴随隧道开挖的整个过程,因洞内条件的限制,洞内开挖断面的测量放样工作占用的时间不少,直接影响着隧道的施工安全、进度。文中通过对待测断面坐标系中的坐标与隧道三维坐标的关系,编制简易的程序,利用简易普及的全站仪进行数据输入、分析,能快速地给出待测断面的坐标,通过几尾隧道的施工放样实践,收到了较好的效果。

Application of Express Measurement in Tunnel Construction

The survey work associated with the whole process of tunnel excavation, due to conditions inside the cave, inside the cave excavation cross-section measurement of the time taken up by lofting a lot of work, directly affect the safety of tunnel construction, progress. In this paper, measured cross-section through the treatment coordinate system of coordinates with the tunnel of the relationship between three-dimensional coordinates, the preparation of simple procedures, the use of simple total station popular for data input, analysis, and can quickly give the coordinates of test section, through the end of the tunnel a few construction lofting practice, and received good results.
