摘要
利用甘肃与四川4个钻孔应变台的资料进行受力分析后发现:中国西部存在着统一的应力场,2001年11月14日昆仑山口西8.1级地震破裂带的力学特征与这个统一应力场相一致.这些台的应变资料在震前都普遍存在明显的短临异常.
It is found that an uniform stress field is exists in west of China by analysising the data of borehole strain from Wudu,Gaotai stations in Gansu province and Panzhihua,Xichang stations in Sichuan province,and the stress field is consistent to the mechanical charactor of deformation belt of west to Kunlun Mountain Pass MS8.1 earthquake on Nov.14,2001.All the strain data in 4 stations show the obvious shortterm anomaly before the 8.1 earthquake.
