本文运用有限单元方法反演了松潘、平武(以下简称松平)三次强震的迁移过程。初步探讨在均匀边界外力作用下沿虎牙关断裂应力场调整与地震活动的关系。计算结果表明:松平地震活动明显受近东西向区域应力场控制,而且与震区特定边界条件密切相关。 In this paper, the finite element method is used to invert the migration process of the three strong earthquakes in Songpan and Pingwu (hereinafter referred to as Songpan). Preliminary study on the relationship between the adjustment of stress field along the fracture of the hump and the seismic activity under the action of the uniform boundary force. The calculation results show that the Songping seismic activity is obviously controlled by the stress field in the near east-west region, and is closely related to the specific boundary conditions in the earthquake area.
