移动三维激光测量系统在地铁运营隧道病害监测中的应用研究

随着我国轨道交通建设事业的蓬勃发展，三维地理信息系统在地铁隧道相关的竣工测量、变形监测等方面逐步得到应用，越来越受到地铁工程建设和管理部门的重视。由于地铁隧道工程的复杂性，采用传统方法进行运营隧道监测需要花费大量的人力、物力和时间。为了适应地铁建设和运营管理部门对地铁工程信息化、三维可视化工作的迫切要求，本文提出了一种集成多种传感器于一体的移动三维激光测量系统。该系统集成了高精度三维扫描仪及编码器等传感器，能快速、高精度地获取隧道内轮廓断面尺寸，通过配套的软件处理，高效地对限界、断面轮廓及隧道变形进行分析。通过在实际项目中应用验证表明，该方法能有效地解决地铁隧道病害监测中的实际问题，可供同类地铁工程项目参考借鉴。

Research on application of mobile 3D laser measurement system in subway operation tunnel disease monitoring

With the continuous development of rail transit construction,the three-dimensional geographic information system is gradually applied in subway-related completion measurement, section measurement and deformation monitoring, which is increasingly favored by urban construction and metro management departments.Due to the complexity of subway management,it takes a lot of time and people to conduct operational monitoring using traditional methods.In order to meet the urgent requirements of the urban planning department and the metro management department for information and 3D visualization of Subway engineering,this paper proposes a mobile three-dimensional laser measurement system integrating multiple sensors.The system integrates sensors such as high-precision 3D scanners and encoders.which can get the profile size of the tunnel quickly and precisely. And can analyse limits, section profiles and tunnel deformations efficiently through complementary software processing.Through the actual project test,the results show that this method can effectively solve the practical problems in subway tunnel disease monitoring, and can be used as a reference for similar subway projects.
