利用漳州深井4分量钻孔应变求测区应变场

REGIONAL STRAIN FIELD COMPUTING BASED ON DATA FORM 4 COMPONENT BOREHOLE STRAINMETER OF ZHANGZHOU

摘要: 利用漳州深井形变综合观测中的4分量钻孔应变观测数据,计算了测区的主应变大小和方向。计算得到的上下两个端面的主应变方位角都在170°附近变化,近东西向性质明显。与利用多个地震求解综合节面解推断出的构造应力场一致。

Abstract: Regional strain filed is computed from the 4 component borehole strain observation data of Zhangzhou station.The magnitudes and direction of the principal strain is given.The direction of the principal strain on up plane and low plan are about 170 degrees, which is consistent with what the results of composite plane solution obtained from moderate intensity seismicity in Fujian area.The direction of regional principal strain is EW.
