摘　　要：区域地面沉降会对在建和运营中的高速铁路产生影响,掌握高速铁路沿线地面沉降状况是防治和减缓其影响的基础工作。阐述了建立高速铁路区域地面沉降监测体系的原则与方法,并以京津城际高铁为实例,基于系统调查基础上的地面沉降危险性分区评价成果,提出了构建包括地下水动态监测、GPS、InSAR、水准测量、分层标测量的监测体系框架及其重点内容与关键环节。Regional land subsidence affects both the construction and operation of high-speed railways. Knowledge of landsubsidence conditions along a high-speed railway is a fundamental requirement if the impact of such subsidence is to becontrolled and mitigated. This article presents the principles and methods of building a regional land-subsidence monitoringsystem for high-speed railway, using as an example the Beijing–Tanjin inter-city high-speed railway. According to theresults of a systematic assessment of land subsidence risk, it is proposed that a monitoring system framework that includesgroundwater dynamic monitoring, GPS, InSAR, leveling, and interferometry should be constructed.
