摘要
本文全面论述了岩石Ｋａｉｓｅｒ效应测定地应力的几个关键问题，划分了不同岩石的声发射特征类型，建立了岩石单、三轴Ｋａｉｓｅｒ效应特征值关系模型，分析了岩石Ｋａｉｓｅｒ效应多期性特征及记忆衰退机理。在此基础上对辽河油田静５２块各测点地应力进行了确定，其结果反映了本区地应力的总体特征。
This paper discusses several problems of rock Kaiser effect in determining groundstress.The acoustic emission types of various rock have been classified. The relationship model of rock Kaiser effect characteristic stress between uniaxial and triaxial compression has been founded. The authors have analyzed the multiple phase characteristics of rock Kaiser effect and the mechanism of memory losing. According to this, the ground stresses at each testing point in Block 52 of Jinganpu Oilfield have been determined, the results reflect the general characteristics of ground stress in this region.
