华北地区断层运动与三维构造应力场的演化
|
摘要
利用华北地区断层形变测量资料 ,通过三维有限元模型 ,数值模拟了华北地区三维构造应力场的演化过程 ,得到了 1 986～ 1 997年以一年为时间尺度的演化图象 ,并分析了应力场的演化特征 ;结合华北地区该时间段内的地震活动性 ,初步探讨了应力场的演化过程与地震活动性的关系 .
Based on data of fault movement surveying, we simulate the evolution process of three dimensional stress field in North China by three dimensional finite element method. Evolutional patterns in one year time scale from 1986 to 1997 have been illustrated and the evolution characteristics of stress field have been analyzed. In comparison with the seismic activity among that time interval in North China, we have primarily discussed the relationship between the evolution of stress field and seismic activity.
