摘要 城市轨道交通在我国经济社会发展建设中正处于加速发展阶段,地铁隧道内部施工参数测量工艺的革新对此具有十分重要的意义。为保证整个隧道施工工艺高效、高质量地完成,克服传统隧道施工参数测量方法测量工艺复杂、测量精度不高,易受隧道内部复杂环境影响等缺点,设计开发一款基于二维激光雷达的智能激光雷达测量小车,对隧道剖面进行360度全方位、高精度的不断扫描,并将检测数据返回测量小车内仓的核心板,待核心板处理后得到隧道剖面的拟合曲线,并计算出施工参数。实践表明,采用智能激光雷达测量小车无论是在施工参数测量精度还是节省施工工艺所需人力、物力资源等方面都得到了很好的提高,满足了施工的需求。这项研究成果成功应用于兰州地铁1号线项目施工现场,节省了人力物力资源,大大提高了施工效率和进度。 Urban rail transit is in the stage of accelerating development in China’s economic and social development,and it is of great significance for the innovation of construction parameters measurement in metro tunnels. In order to ensure the efficient and high-quality completion of the entire tunnel construction process,overcoming the traditional tunnel construction parameter measurement method,the measurement process is complex,the measurement accuracy is not high,and it is vulnerable to the complex environment inside the tunnel. An intelligent laser measuring car based on two-dimensional laser is designed and developed. The tunnel section is continuously scanned 360 degrees in all directions and with high accuracy. The measured data are returned to the core board of the measuring car. After the core board is processed,the fitting curve of the tunnel section is obtained and the construction parameters are calculated. Practice has shown that the use of intelligent lidar to measure the car has been greatly improved in terms of construction parameters measurement accuracy and manpower and material resources required to save the construction process,and has met the construction requirements. Successfully applied to the construction site of Lanzhou Metro Line 1 project,saving manpower and material resources,greatly improving construction efficiency and progress.
