中文摘要:
      临近交叉施工可能会对运营期高速铁路隧道结构产生影响,危及高速铁路安全运营,对受下穿工程施工影响的运营期高速铁路隧道进行实时变形监测。通过实时监测和人工周期监测进行比对分析,两者监测成果具有良好的一致性。各断面监测点沉降变化量均在Ⅰ级预警限值(1.6 mm)内,说明监测期间下穿工程施工未对运营高铁隧道结构造成显著影响。证明该实时监测系统能够满足运营期高铁变形监测的远程实时性要求,且具有较高监测精度。
英文摘要:
      The construction close to another construction site may have an impact on the structure of the high speed railway tunnel in operation, endangering the safe operation of the high speed railway, in which case monitoring the real time deformation of the high speed railway tunnel in operation affected by the construction of the under passing project has to be performed. Through comparing and analyzing the data obtained from the real time monitoring and the artificial cyclical monitoring, the monitored results of the two are found to be in good agreement. The change in settlement of each section monitoring point is found to be within the level I early warning limit (1.6 mm), which indicates that the under passing construction has no significant impact on the operation of the high speed railway tunnel structure in the monitoring period. It is proved that the real time monitoring system can meet the requirements of long range real time deformation monitoring of high speed railways in operation, and has high monitoring accuracy.
