| 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. |
