摘要 地铁隧道横向贯通测量精度是城市地铁建设中的关键环节,直接影响工程质量和安全。探讨提高贯通测量精度的新方法,以降低施工风险,提升地铁建设效率。以某地铁建设工程为研究对象,重点考察了陀螺定向测量技术在地铁建设中的应用效果。研究过程包括在实际工程中部署陀螺定向测量设备、进行多次测量试验并收集数据、对测量数据进行统计分析计算误差范围,最后将结果与国家标准进行对比。研究结果表明:在本项目中陀螺定向测量的误差为±1.79″,符合《城市轨道交通工程测量规范》的精度要求,结果证实了陀螺定向测量作为辅助定向测量技术的可靠性和实用性。 The accuracy of transverse penetration measurement in subway tunnels is crucial in the urban subway construction and it directly affects the quality and safety of the subway tunnels.The methods to improve measurement accuracy are explored in this study to reduce construction risks and enhance efficiency.Focusing on a specific subway project,the application effects of gyroscope directional measurement technology are examined in the research.Deploying the technology in engineering,conducting experiments and collecting,analyzing data,calculating the range of error are involved in the research process and finally having the results compared to the national standards.The findings show that the measurement error is±1.79″which meets the requirements in accuracy of the"Code for Urban Rail Transit Engineering Surveying"and confirms the technology's reliability and practicality as an auxiliary orientation measurement technology.
