摘　　要：本文以新建济青高铁施工对既有胶济客专线路路基沉降影响的现场实践为研究对象,通过分析静力水准仪的安装及监测测量原理,以及在路基沉降监测工作中具有的优点,将静力水准仪自动沉降监测系统应用于新建线路济青高铁对既有高速铁路胶济客专的沉降监测工作中,现场通过在自动沉降监测系统中设定预警阈值,对路基沉降超限情况进行预警,从而实现既有线路路基沉降自动监测与预警,提高了沉降监测的自动化、准确性和实时性,为相似工程施工路基沉降监测工作积累经验。In this paper, the site practice of the construction of Jiaoji high speed railway is studied in the light of the site practice of the Jiaoji high speed railway. By analyzing the principle of the installation and monitoring of the static level, and the advantages of the subgrade settlement monitoring, the static leveling automatic settlement monitoring system is applied to the settlement monitoring of the existing high speed railway Jiaoji railway by the new line JiQing high speed railway. By setting early warning threshold in the automatic settlement monitoring system, the monitoring and early warning of subgrade settlement of subgrade is realized, thus the automation, accuracy and real time of settlement monitoring are improved, and experience for subgrade subsidence monitoring in similar construction is accumulated.
