| Abstract: | According to the plate tectonics theory and 3D finite element modeling,considering the historical evolution of stress field in North China,the variation of internal tectonic stress field in North China are simulated numerically when applied forces on the boundary of north China have changed.Changes of direction of collisions of Pacific plate and India plate with Eurasian plate induce important loading-unloading effect.If the direction of applied forces from Pacific plate turns southwards that leads to the loading in the north part and unloading in the southeast part of North China,whereas the direction of applied forces from Pacific plate turns northwards that leads to the unloading in the north part but loading in the southeast part of North China.The direction of applied forces from India plate turns southwards that leads to the loading in the middle region of Shanxi and Tangshan-Bohai aeras,whereas the direction of applied forces from India plate has turned northwards that leads to the loading in the east and south part and unloading in the mid-west part of North China. |
