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

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.
