| 摘 要： | 本文通过近年来,在京津唐地区取得的大地测量资料,研究本区现代构造运动,指出了北北东—北东向、北西向及东西向三组构造最为活动。它们是受近于水平方向北北西—南南东向主张应力和北东东—南西西向主压应力的应力场所控制,并以主张应力大于主压应力的作用方式出现;而又受深部构造的断块上拱和断陷的影响

CRUSTAL DEFORMATION AND RECENT TECTONIC MOTION IN THE BEIJING-TIANJING-TANGSHAN REGION |
| |
| Abstract: | This paper deals with the recent tectonic motion in this region using the geodetic data, indicating three groups of the most active structures in NNE-NE-NW directions. They have been subjected either to influence of uprising and downfaulting blocks at depth in the earth or to constraint of principal extensional stress field in NNW-SSE direction and principal compressional stress field in ENE-WSW direction, the former being larger than the latter |
