摘要
为了准确测出隧道开挖的实际轮廓线,计算出精确的超欠挖量,根据使用的仪器不同,对目前隧道断面测量主要采用的断面仪法、全站仪法和三维激光扫描仪法三种方法的作业流程、工作效率及测量精度等情况进行了对比分析,得出了一些有益的结论。
The purpose of tunnel section measuring is measuring the actual contour line of tunnel excavation accurately,and calculate overbreak and underbreak quantity. According to different apparatus,the method of tunnel section measuring includes profiler method,total station method and 3D laser scanner method. This paper analyzed the working process,the working efficiency and the measurement precision,and some benefi-cial conclusions are obtained.
