辽宁及邻区应力场模拟中远场应力的确定
FAR-FIELD STRESS DETERMINED IN SIMULATED STRESS FIELD IN LIAONING AREA AND ITS ADJACENT
【摘要】 本文在讨论辽宁、渤海及沿岸地区的原地应力测量、地震震源机制解,小震综合断层面解、形变资料反演的应力场资料基础上,对各资料作了综合加权处理,求得本地区的远场水平应力方向、大小及随深度变化,在应力场数值模拟中以此作为力的边界条件。
【Abstract】 Based on the analysis of in-situ stress measurements, mechanism solution of earthquake foci, comprehensive solution about the fault plane of small earthquakes, stress field inverted by deformation data in Liaoning area and its adjacent, the data are comprehensively processed by weight. It is obtained that the horizontal stress direction and its size varied in pace with depths, and it can be regarded as the boundary condition of force in simulated numerical stress field .
