摘要
通过对地应力实测资料的分析,论述了套芯法地应力测量中产生钻孔轴向主应力偏高现象的原因,提出了克服此类现象的针对性措施。
According to the analysis of the on-sspot surveyed data of the ground stress the article discusses the causes why the axial main stress of the drilling rises in the ground stress survey by the core drilling method.To counter this phenomenon , the effective measures are put forward.
