广兴高速下穿南昆客专高铁大桥安全监测分析

Analysis of Safety Monitoring for the High Speed Railway Bridge Undercrossing the Nankun Passenger Dedicated Line of Guangxing Expressway

为确保南昆客专的设备设施状态安全可靠,采用全站仪对云桂铁路薄峰1号双线大桥桥墩、抗滑桩以及边坡的沉降与位移进行监控测量,重点对标段内桥梁、抗滑桩及边坡进行变形监测,将监测对象的变化趋势及时提供给运营管理单位、业主单位及施工单位等,以便于各参建单位及时判断并预警,将施工对既有线的安全影响降至最低,保证既有线的运营安全。

To ensure the safety and reliability of the equipment and facilities of Nankun Passenger Dedicated Line,RTK is used to monitor and measure the settlement and displacement of the piers,anti slip piles,and slopes of the Baofeng No.1 double track bridge on the Yungui Railway.It focuses on monitoring the deformation of bridges,anti-skid piles,and slopes within the bid section,and timely provides the changing trends of the monitoring objects to the operation management unit,owner unit,and construction unit,so that all participating units can make timely judgments and warnings,minimize the safety impact of construction on the existing line,and ensure the operation safety of the existing line.
