摘要
为解决铁路隧道运营维护中钢垫梁的稳定性监测,以达到监测数据准确实时反馈,为既有线运营过程中施工安全提供参考依据,以某铁路隧道隧底整治工程为背景,采用精密光栅位移计配合光栅解调仪、GPRS传输模块监测钢垫梁位移数据,静力水准仪配合采集软件监测钢垫梁沉降数据,利用计算软件实时分析以实现钢垫梁的稳定性监测,并采用TM50测量机器人对钢垫梁上轨道坐标进行对比监测,并对比分析各项监测数据,验证其监测精度。提出了一套铁路隧道运营维护中钢垫梁稳定性的监测方法,解决了常规方法不能实时准确反馈监测数据的难题,为铁路隧道运营维护施工安全提供了保障。
The stability monitoring of steel cushion beam during operation and maintenance of railway tunnel and the real-time accurate feedback of monitoring data are of great significance to the construction safety of existing operation railway line.Hence,the displacement data of steel cushion beam of a railway tunnel is monitored by accurate grating displacement meter with grating demodulator,GPRS transfer module and static leveling instrument with acquisition software;the monitoring data are analyzed by calculation software in real-time to guarantee the stability of the steel cushion beam;the track coordinates on the steel cushion beam are monitored and compared by measuring robot;and the monitoring data are analyzed to verify its accuracy.A set of monitoring methods for the stability of steel cushion beams during railway tunnel operation and maintenance is put forward,which realizes real-time feedback of the monitoring data and guarantees the safety of operation and maintenance of railway tunnel.
