摘要 全面、快速、精确地掌握地铁隧道结构的结构健康情况,对于隧道结构维护和保障地铁线路的正常安全运营具有十分重要的意义。利用GRP5000激光全息成像扫描系统能无损、快速地获得地铁结构综合数字图像和点位坐标等信息,使用这些数据信息,可以对地铁结构的整体状态、病害、限界、错台、变形、收敛情况等进行分析和评价并生成技术报告,满足地铁结构健康检测的相关需求。 It is very important to precisely,efficiently,speedly and comprehensively master the health situation of metro structure for the maintenance of tunnel structure and guarantee of subwayoperation. We can get the subway structure integrated nondestructive,digital image and point coordinates and other information by using GRP5000 laser holographic scanning and imaging system. The data can make us easier to analyze the sate of structure,disease,ovality,slab staggering,tunnel gauge,deformation,closure and so on and generate the report in order to meet the demand of subway structure health investigation.
