摘　　要：在铁路施工过程中对几何参数的精确测量是至关重要的环节。传统上测量工作主要由水准仪、全站仪等设备完成,而这些传统方法已无法充分满足现代大型铁路施工的精度需求。本文首先阐述三维激光扫描技术的工作原理及特点,随后结合具体工程案例探讨了该技术在铁路施工领域的实际应用。通过三维激光扫描点云控制在铁路轨面几何形态、桥梁隧道结构监测、地貌土壤稳定性施工中的应用,为隧道施工测量、质量控制和结构检测提供解决方案,为运营维护快速检测提供技术支撑。Accurate measurement of geometric parameters is a crucial step in railway construction.Traditionally,measurement work was mainly completed by equipment such as level gauges and total stations,but these traditional methods can no longer fully meet the accuracy requirements of modern large-scale railway construction.This article first elaborates on the working principle and characteristics of 3D laser scanning technology,and then explores the practical application of this technology in the field of railway construction through specific engineering cases.The application of 3D laser scanning point cloud control in railway track geometry,bridge and tunnel structure monitoring,and geomorphic soil stability construction provides solutions for tunnel construction measurement,quality control,and structural testing,and technical support for rapid operation and maintenance testing.
