摘要/Abstract

摘要： 地铁施工、运营阶段的监控量测,可有效保障隧道结构的稳定与周围环境的安全。现有的收敛计、全站仪等变形监测手段,虽然可以得到高精度的观测数据,但获取的监测点位过于稀疏,难以全面反映隧道整体的形变特征。本文将三维激光扫描技术用于地铁隧道形变监测,提出了基于激光点云的隧道断面连续提取与形变分析方法,并对提取的两期断面进行了形变分析,试验结果表明该方法能够更直观地表现隧道整体变形,研究成果可为隧道形变动态监测提供借鉴。

Abstract: Monitoring measurement of subway in the stage of construction and operation can ensure the stability of tunnel structure and the safety of its surrounding efficiently. Although existing monitoring measures such as using convergence meter or total station can help to obtain high precision monitoring data, received deformation monitoring points are too sparse, which results in difficulty in reflecting overall deformation characteristics of tunnel. This paper proposed a method for continuously vertical section abstraction and deformation analysis for subway tunnel based on terrestrial point clouds through three-dimensional laser scanning technology applied to deformation monitoring of the tunnel, and made deformation analysis of abstracted two-period section data. The results of the research showed that global deformation of tunnel was reflected more visualized through this method and provided a reference for the dynamic monitoring of tunnel deformation.

Key words: subway tunnel, section extraction, deformation analysis
