激光断面仪在隧道断面检测中的应用

摘要

介绍了隧道激光断面仪检测的基本原理和使用方法，以内蒙古隆盛隧道为工程背景，使用激光断面仪对初期支护断面轮廓和二衬断面进行了检测，对检测结果进行了总结，分析检测出的断面轮廓数据所出现的偏差。%The basic principles and the methods of the laser profiler are analyzed in this paper.Based on the Inner Lngsheng tunnel engineering,laser profiler is used to examine initial support sections and secondary lining sections.Test results are summarized and analyzed to find the deviation of the data of the two cross-sectional profile detected.It provides experience for similar section detection of highway tunnel.
