摘　　要：详细介绍了高速铁路无砟轨道精密施工测量新技术的总体思路、目的和要求、数学模型和关键技术。通过在不同类型无砟轨道施工现场试验与国内外其他同类产品的偏差比较,验证其精度和稳定性。该技术在多个工程项目的轨道精调测量中得到实践应用,保证了测量精度,充分利用既有仪器设备,减少仪器设备再投入,为今后类似工程施工提供有效技术支持,其社会、技术、经济效益明显。This article describes in detail the general idea, purpose and requirement, mathematical model and key technology of new construction technology for precision construction measurement of ballastless track in high-speed railway developed by our company. Through the comparison between different types of ballastless track construction site tests in our company and other similar products at home and abroad, its accuracy and stability are verified. The technique has been applied in the measurement of track precision of several projects, and it could provide effective technical support for similar project construction in order to ensure the measurement precision, make full use of the existing instruments and equipment, and reduce the input of instruments and equipment, and its social, technical and economic benefits are obvious.
