摘　　要：北京是轨道交通工程在建项目最多的城市,沉降监测对地铁工程的安全施工有着重要意义,同时监测数据能够直接用来评价地铁施工对地表环境的影响。本文重点论述了北京地铁沉降监测的方法与技术要求,介绍了所用仪器数据文件的格式,详述了数据处理和统计分析。最后,文章给出了变形预报分析的数学方法,并说明了其现实意义。The ground subsidence observation is the most important thing for the safety of subway construction. The surveying data can evaluate the construction impact on the ground surface and the environment. The topics discussed in this paper include the method of subsidence observation used in Beijing subway construction, the data file format of Trimble DiNi12, the data processing of subsidence observation and the deformation analysis for ground and buildings affected by the mentioned construction. The paper also gives a way to forecast the deformation value.
