从应力解除资料反演中国东部郯庐断裂带区域应力场方向
ON THE DIRECTION OF THE REGIONAL STRESS FIELD IN THE TANLU FAULT REGION OF EAST CHINA BY INVERSION OF THE DATA OF INSITU STRESS MEASUREMENTS
-
摘要: 本文用二维非线性有限元法,取郯庐带一个水平剖面进行了模拟计算.根据该区原地应力测量资料反演了区域应力场方向.推断区域应力场主压应力方向为北东80——90.Abstract: This paper describes the results of simulated computation along a horizontal section of the Tanlu fault region by the two-dimensional non-linear finite element method. By inversion of the data of in-situ stress measurements the direction of regional stress has been obtained. It is inferred that the direction of the principal compressional stress of the regional stress field is NE80-90.
