摘要: 隧道结构断面测量的目的是准确测出隧道开挖的实际轮廓线,并与设计轮廓线进行对比分析,从而计算超欠挖量。断面测量根据使用的仪器不同主要有断面仪法、全站仪法和三维激光扫描仪法,本文对这3种方法的工作效率及测量精度等情况进行了对比分析,并得出了一些有益的结论。

Abstract: The purpose of tunnel section measurement is to accurately measure the actual contour of the tunnel excavation and compare it with the design contour to calculate the over-underage. Section measurement according to the different instruments used, there are mainly cross-section method, total station method and 3D laser scanner method. This paper compares the working efficiency and measurement accuracy of these three methods, and draws some useful results in conclusion.

Key words: 3D laser scanning technology, total station profiler, tunnel section, overbreak-shortbreak
