Numerical Simulation of Tectonic Stress field in the southeast of the Qinghai-Tibet Plateau

摘要

The tectonic stress field plays an important role in the research of crustal stability, fault activity and the geological disaster effect. On the basis of related geological data, ANSYS and FLAC3D are applied in this paper to set up a reasonable geological structure model and boundary conditions, aiming at making a numerical simulation analysis of tectonic stress field in the southeast of the Qinghai-Tibet plateau. The result and the measured data fit better, which provides a reference for the further study of the project.
