本文从实验角度探讨了印度洋板块边界力的不同作用方式对欧亚大陆应力场的影响。结果表明,印度洋板块带主动性的向北顶撞是造成我国西部及邻区强震三角域分布的直接原因,随边界力的作用方式由正北向北东方向偏转,大陆内部相对应力集中区条带也随之向东偏移。 This paper discusses the effect of different modes of Indian Ocean plate boundary force on the stress field in Eurasia from the experimental point of view. The results show that the collision of the Indian Ocean plate with the active North China is the direct cause of the distribution of the triangular earthquakes in the western and adjacent areas of China. The boundary force acts from northeast to northeast, and the internal stress concentration zone It will also shift to the east.
