Scope

Scope: Urban railroad engineering measurement; Main technical content: 1. This standard establishes a comprehensive technical system for urban railroad engineering measurement, filling the gap in technical standards for urban railroad engineering measurement in China. 2. Combined with the control measurement situation during the survey, design, and construction of new urban railways and the full life cycle characteristics of urban railroad construction and operation, the standard adopts the "three-network integration" measurement concept during its preparation. It reasonably sets technical requirements and accuracy levels for precision control networks of various grades, fully considering their economic feasibility and operability. 3. It proposes concepts such as full-circular direction distance observation method, simultaneous opposite indirect height difference method, and corner-side plane control network, and specifies measurement methods and accuracy requirements. 4. Combined with the development of surveying and mapping technology and the current management mode of urban railways, it includes content such as real-scene 3D modeling, third-party measurement, and third-party monitoring. 5. The standard comprehensively applies the most cutting-edge surveying and mapping technologies, including GNSS, total stations, digital levels, track measuring instruments, and remote sensing mapping, which are advanced, applicable, and more operable, thus promoting the advancement of urban railroad engineering measurement technology and improving the quality and efficiency of urban railroad engineering measurement. 6. The content is written in reference to relevant national standards and other industry standards, and some measurement methods and accuracy indicators have been revised, improved, and supplemented, which demonstrates its relevance and independence.
