A PRELIMINARY ATTEMPT FOR INVERSION OF TECTONIC STRESS FIELD IN TIBETAN PLATEAU WITH GEODETIC DATA

Xu Caijun, Chao Dingbo, Liu Jingnan, Tao Benzao, Zhang Dehan (Wuhan Technical University of Surveying and Mapping, 430070)  
The method of inversing the tectonic stress field with geodetic data is discussed in the paper. Based on the geological and geophysical data, a three dimension elastic finite element model is set up to simulate the tectonic stress field in Tibetan plateau. The displacements provided by GPS and levelling data act as boundary constraints on the earth surface in the model. The simulant results show that the main part of tectonic deformations in the plateau are the compression in N S direction, the tension in E W direction and vertical upheaval, and the present tectonic stress field is predominated by the collision between the Indian plate and the Eurasian plate.
