摘要
一个已经破裂的岩体在晚期构造应力场中所产生的变形主要是沿老断裂面滑移为其特征。系统测量锦屏山地区微断层的位移要素,并经计算获得四期新构造应力场的平均应力张量,其中NW—SE向应力场和NE—SW向应力场为该区的两期主要构造应力场。
The deformation of rupture rock in post-tectonic stress field is characterized by slipping along its previous ruptures. Displace- memt parameters of microfaults systematically measured, in the Jinping Mountain area are calculated and the mean stress tensors of the four phases neotectonic stress field are obtained, and among the four phases the NW-SE and NE-SW direstion stress fields are the poincipal ones.
