| 摘 要： | 地铁隧道结构断面测量的目的是准确的测出隧道开挖的实际轮廓线,并与设计进行对比从而计算超欠挖量。断面测量根据使用的仪器不同主要有断面仪法、全站仪法(机载程序或PDA控制)和三维激光扫描仪法,本文对这三种方法的数学模型、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 subway tunnel structure section measuring is measuring the actual contour line of tunnel excavation accuralely, and compared with the design line and calculateoverbrcak and underbreak quantity. Tunnel measurement method is including profiler method ,total station（onboard program or PDA control） and 3D laser scanner method. This paper analyze the mathematical model, lhe working efficiency and the measurement precision, and some beneficial conclu sions are obtained. |
