摘　　要：在佛山地铁某区间隧道竣工验收中引入三维激光扫描仪进行零状态普查,形成了一种快捷有效的城市轨交隧道结构状态普查方法。可以高效、真实、高精度地检测出隧道结构零状态的表观及几何形态,进而全面真实地反映轨交隧道初始状态;通过统计分析三维扫描所生产的结构状态数据,评估轨交隧道安全状况,为后续运营维护提供翔实的基础数据。In the completion acceptance of a certain section of the Foshan Metro tunnel,the 3D laser scanner was introduced to conduct a zero-state general survey,forming a fast and effective method for urban rail transit tunnel structural state general survey.It can detect the appearance and geometry of the tunnel structure in zero state efficiently,truly and high precision,and then comprehensively and truly reflect the initial state of the rail transit tunnel,providing detailed basic data for subsequent operation and maintenance.

关 键 词：隧道结构零状态普查 三维激光扫描仪 表观及几何形态 轨交隧道安全状况
