渭河盆地中部区域地壳形变及应变的分布特征
ON CRUSTAL DEFORMATION-STRAIN CHARACTERISTICS OF CENTRAL REGION OF WEIHE BASIN
摘要
Abstract
On the basis of the "digital seismic network engineering" GPS monitoring results, and combined with regional tectonic features,the 2D finite element model of the Weihe basin central region is built. According to the above, the present crustal deformation-strain distribution characteristics of the studied area are obtained. The results show that the Xi' an-Xianyang area is of significantly high value of the surface expansion and mainly tensile strain within the area, the value respectively reaches more than 2. 0 × 10-6 /a and 3.5×10-6/a. Thus the present crustal tensile tectonic activity of Xi' an-Xianyang area is strong.关键词
