RESEARCH ON FAULT MOTION AND SEGMENTATION CHARATERISTIC OF KOUQUAN FAULT IN DATONG BASIN BY NUMERICAL SIMULATION
摘要
Abstract
Using the GPS observation results of 1999-2007 and 2009-2011 as the constraints,and based on the method of three-dimensional finite element,the fault motion and segmentation characteristic of Kouquan fault in Datong basin were analyzed.The results show that the fault is more active in the middle part than the either side.The right-lateral velocity of the fault is 0.8 mm/a and its normal velocity is almost 1.5 mm/a in the middle part of the Kouquan fault.关键词
