摘要
为确保复杂艰险山区铁路的施工及运营安全,文章对三维激光扫描技术进行研究与创新,结合三维激光扫描精度指标研究提出复杂艰险山区铁路三维激光扫描标准差标准,探讨在复杂艰险山区铁路在施工及运营阶段如何利用高精度点云数据提取路基及隧道工程等构筑物三维坐标进行施工质量评价和变形监测评价,在运营阶段如何利用高精度云数据提取铁路轨道几何参数以及轨道沿线设施等为运营维护提供检测数据,研究成果课为复杂艰险山区铁路施工及运营维护快提供技术支撑。
In order to ensure the safety of the construction and operation of the Construction of Complex and Difficult Mountains Railway,the 3D laser scanning technology is studied and some innovations are made in this paper;the standard deviation for the 3D laser scanning of the Construction of Complex and Difficult Mountains Railway is put forward on the basis of the research on the 3D laser scanning accuracy indexes;the method to use high-precision point cloud data to extract the 3D coordinates of structures such as subgrade and tunnels for construction quality evaluation and deformation monitoring evaluation,as well as the method to use high-precision cloud data to extract geometric parameters of railway tracks and facilities along the track for operation and maintenance are also discussed.The research results can provide technical support for the construction,operation and maintenance of the Construction of Complex and Difficult Mountains Railway.
