摘要
地铁隧道断面测量的目的是准确地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。地铁隧道断面测量方法众多,并且各有优缺点。论文对常用的断面仪法、全站仪法和三维激光扫描法的作业流程和效率进行了简要介绍,并对其进行对比分析。
The purpose of the subway tunnel structure section measurement is to accurately measure the actual contour of the tunnel excavation and comparing with the design,to calculate the amount of over excavation. There are many methods to measure the cross-section of metro tunnel, and each has its own advantages and disadvantages. Measuring accuracy and working efficiency of the commonly used cross-section method, total station method and 3D laser scanning method are briefly introduced.
