摘要: 近年来,为保障铁路运输安全,利用北斗高精度定位技术的铁路基础设施位移监测方法得到了广泛研究。文章介绍了北斗高精度监测的原理,详细阐述了基于北斗定位技术的铁路基础设施监测系统的架构、功能和接口设计,并通过现场监测数据对该系统的功能进行了验证,验证结果表明,该系统能够实现毫米级的监测精度,可为铁路基础设施位移监测提供技术支撑。Abstract: In recent years, in order to ensure the safety of railway transportation, the displacement monitoring method of railway infrastructure using Beidou high-precision positioning technology has been widely studied. This paper introduced the principle of Beidou high-precision monitoring, expounded in detail the architecture, function and interface design of the railway infrastructure monitoring system based on Beidou positioning technology, and verified the function of the system through on-site monitoring data. The results show that the system can achieve millimeter level monitoring accuracy, and can provide technical support for railway infrastructure displacement monitoring.

表 1 监测对象形变/位移趋势及巡检建议
监测对象 形变/沉降趋势 巡检建议 高路堤边坡 存在明显沉降位移趋势,监测到最大沉降约10 mm,平均沉降约8 mm 按相关规定,对该工点进行检查,加固。 隧道仰坡 未监测到明显沉降趋势 按相关规定,定期巡检该工点,建议关注5号、8号监测点环境 桥梁 未监测到明显形变趋势 按相关规定,定期巡检该工点 基站通信铁塔 未监测到明显倾斜趋势 按相关规定,定期巡检该工点 -
