为提高首都北京的地质安全，在探索首都圈地区深孔地应力测量与实时监测在地震地质研究中应用思路方法的基础上，制定首都圈地区深孔地应力测量与实时监测总体规划，通过不同关键构造部位深孔地应力测量、实时监测以及测量监测结果的对比分析，揭示首都圈地区地壳浅表层现今地应力环境，捕捉中强地震发生的地应力前兆异常。平谷地应力实时监测台站全程记录了2011年3月11日日本9．0级大地震及其前后地应力大小和地下水位相对变化，尤其是大地震发生的前兆应力变化，为地震地质研究积累了宝贵的数据。通过首都圈地区不同关键构造部位地应力测量与实时监测数据的对比分析及2012年和2013年唐山及其周围地区地震发震背景的综合研究，发现唐山-滦县-昌黎一带，尤其是昌黎地区，现今构造活动异常，需要重点关注其未来发展趋势。

In order to enhance the geologic safety of Beijing,we have decided to approach it respectively in three steps:approaching the thoughts and methods on seismogeology research by deep borehole crustal stress measuring and real-time monitoring;primarily establishing the general plan for developing deep borehole crustal stress measuring and real-time monitoring at key tectonic locations in the Beijing region;analyzing and contrasting the measuring and monitoring data to obtain the crustal stress information of an earthquake.The crustal stress measuring and monitoring data primarily reflect the present crustal stress backgrounds in shallow upper crust.The relative variations of crustal stress magnitude and underground water,especially the forewarning crustal stress variations beforeJapan’s Ms9. 0 earthquake on March 1 1 , 2011,were completely recorded at Pinggu crustal stress comprehensive monitoring station,which provides valuable data for seismogeology research. Through analyzing and contrasting the measuring and monitoring data at different key tectonic locations around Beijing,we have found that the data are in abnormal state at Changli county in Hebei Province.In addition,we have holistically studied the causative backgrounds of earthquakes that have happened around Tangshan and its outskirts in 2012 and 2013.From these researches and evaluations,we conclude that the present tectonic activity is abnormal along the zone from Tangshan to Luanxian to Changli,and greater attention should be paid to Changli area.
