摘要
分析了传统监控量测方法在大断面黄土隧道施工中的局限性,提出采用非接触量测的方法对大断面黄土隧道初期支护变形进行监控量测,分析黄土隧道初期支护的变形特点和规律,结果表明,利用非接触量测进行黄土隧道初期支护的监控量测可以克服施工干扰、降低劳动强度,极大地提高了作业效率。
The traditional method of monitoring measuring in the big cross-sections and loessial tunnel construction limitations can not meet the design and specification requirements, the use of non-contact measurement method for big cross-sections and loessial tunnel in the early support to monitor deformation measurement, and analysis of the loessial tunnel in the early support of the deformation Characteristics and laws of the results showed that the use of non-contact t for loessial tunnel in the early support of the Monitoring measurement can be overcome interference, and to reduce labor intensity and greatly improved the operation efficiency
