三维激光扫描技术在轨道交通工程规划核实中的应用

Application of 3D Laser Scanning Technology in the Rail Transit Project Planning Verification

随着城市化进程的加快,很多城市开始兴建服务于城市境内的各种轻型化铁路系统,规划核实测量作为建设工程竣工验收中的一个重要环节,不可或缺。地下部分作为轨道工程项目规划核实的重点,采用传统的测量手段,工作量大、效率低下,甚至无法进行施测。本文以实际项目(南通市轨道交通1号线深南路站)为例,介绍了Leica RTC360三维激光扫描仪在轨道交通工程规划核实测量中的应用情况,包括作业方法、数据处理与应用、精度与效率分析及经验总结,对轨道交通工程规划核实数据采集方法进行了积极的试验。

With the acceleration of urbanization,many cities have begun to build various light rail service systems,planning verification measurement is an important part of the completion and acceptance of construction projects,which is indispensable.As the focus of the planning verification of the rail transit project,the underground part uses traditional measurement methods,which is labor cost,inefficient,and even impossible to measure.Taking the actual project(Shennan Road Station of Nantong Rail Transit Line 1)as an example,this paper introduces the application of Leica RTC3603D laser scanner in the planning verification measurement of rail transit engineering,including operation methods,data processing and application,accuracy and efficiency analysis and experience summary,and actively tests the data collection method of rail transit project planning verification.
