| 英文摘要 | Based on data of principal stress orientation from focal mechanism and of geological features in china, we made pseudo-3d genetic algorithm finite element (ga-fem) inversion to investigate the main forces acting on the chinese continent and adjacent areas which form the chinese tectonic stress field. the results confirm that plate boundary forces play the dominant role in forming the stress field in china, as noticed by many previous researchers. however, we also find that topographic spreading forces, as well as basal drag forces of the lower crust to the upper crust, make significant contribution to stresses in regional scale. forces acting on the chinese continent can be outlined as follows: the collision of the india plate to the nne is the most important action, whereby forces oriented to the nw by the philippine plate and forces oriented to the sww by the pacific plate are also important. topographic spreading forces are not negligible at high topographic gradient zones, these forces are perpendicular to edges of the tibetan plateau and a topographic gradient belt running in the nne direction across eastern china. basal drag forces applied by the ductile flow of the lower crust to the base of upper crust affect the regional stress field in the tibetan plateau remarkably, producing the clockwise rotation around the eastern himalaya syntax. |
