摘要
结合广州地铁隧道沉降监测实例,阐述隧道内沉降测点、差异沉降点的布置和施测方法,以及沉降曲线拟合及分析,讨论隧道结构的沉降情况、规律及成因,为运营隧道的维修管理提供经验。
Based on Guangzhou subway tunnel subsidence monitoring practice,the paper describes the layout of measuring points for tunnel settlements together with measuring points for tunnel differential settlements and the measuring methods,and the settlement curve fitting and analysis.It also discusses the settlements of tunnel structures,settlement regularity and causes of settlements.The practice provides experience for the maintenance management of tunnels.
