GEOMOS自动监测系统在城际铁路隧道下穿既有广深铁路施工中的应用

主要研究城际铁路大断面隧道下穿既有广深铁路枢纽区域的施工过程中,如何快捷高效、无人值守的获得既有铁路设施的实时变形或位移数据,达到自动监测系统指导现场施工的目的。运用GEOMOS自动监测系统,并结合各个施工工况的前后数据进行对比分析,有效地指导开挖施工,确保既有高速铁路运营安全及城际铁路隧道开挖安全。

The Use of GEOMOS Automatic Monitoring System in the Construction of Inter-city Railway Tunnel under the Existing Guangzhou-Shenzhen Railway

This paper focuses on how to obtain the real-time deformation or displacement data related to existing railway facilities in a quick,effective and non-attended manner during the construction of the inter-city railway tunnel with large cross section under the existing Guangzhou- Shenzhen railway joint terminal area so as to guide the site works by the automatic monitoring system. The GEOMOS automatic monitoring system is applied for fast and efficient access to existing railway facility deformation or displacement data,to guide the construction and ensure safe operation of high speed railway and safe excavation of intercity tunnel with the assistance of data comparison and analysis before and after each construction phase.
