喜马拉雅弧边界作用力的变化对中国内陆应力场的影响

Abstract

Abstract: Applying numerical simulation method, the effect of the variation of boundary condition in Burma arc (Eastern arc) and in Pamirsarc (Western arc) on the stress field inside China's inland are studied. Then the relation between the variation of the boundary force in Himalayan and the stress field in China's inland and the earthquake activity is researched. The following conclusions are drawn: The variation of boundary conditions has great effect on the adjustment of stress field in China's inland. Among which, the variation of boundary conditions in Burma arc has greates effect on the pattern of strong earthquake activity in western China. The variation of boundary conditions in Himalayan arc can result in earthquake strong in groups.

Key words: Himalayan arc, Numerical simulation, Boundary condition, Shear stress field
