北京地面沉降目前正处于一个快速发展阶段。本文利用天竺站、望京站和王四营站2005~2012年分层标监测数据分析了年沉降量、不同深度土层变形量及其在总沉降量中百分比构成的多年变化特征，并结合分层地下水位动态变化，对三个站地面沉降多年变化所表现出来的异同点进行了阐述。结果显示：60m以浅地层年沉降量小且波动也小，100m以深地层是主要的压缩层位；不同深度土层变形量及其在总沉降量中比重构成的变化与相应的含水层水位变化幅度密切相关。在无法禁采的情况下，采取一定的限采控采措施使地下水位小幅回升或约束地下水位的下降幅度，将有利于地面沉降的减缓。

Land subsidence in Beijing has now reached a rapid stage of development. Using layered monitoring data for the period 2005-2012 from the Tianzhu, Wangjing, and Wangsiying stations, this paper analyzes dynamic changes in the annual subsidence rate and the rate and percentage of soil deformation at different depths. Using layered monitoring of groundwater levels, the differences and similarities among the three stations were identiifed. Our results show that:(i) the subsidence rate of strata at depths less than 60 m is less than that of deeper layers and is also less variable, while strata at depths greater than 100 m are the main compression layers;(i ) the deformation rate of soil at different depths, and its percentage, is closely related to changes in the corresponding groundwater level. Although it is impossible to completely prevent groundwater exploitation in the near future, land subsidence could be slowed down if groundwater levels could be increased slightly, or the rise and fal control ed by ay least limiting groundwater exploitation.
