用GPS数据研究汾渭盆地构造应力场变化
TECTONIC STRESS VARIATION OF FENWEI BASIN DERIVED FROM GPS DATA
摘要
Abstract
The maximum principal stress and shear in depth 15 km of earth crust in Fenwei basin are computed by using GPS data observed from 2004-2007. The computed results show the following situatuins. 1 ) The distribution of maximum principal stress variation are not uniform that the principal stress increased in mountain area and decreased in basin area. 2)The shear decreased in Baoji-Xianyang and increased in Tangyu-Pucheng.关键词
