由断层滑动资料确定的第四纪构造应力场和晚第三纪以来的地壳形变分析结果， 较好地解释了青藏高原北、东边缘自中新世中晚期以来的地壳动力学演化特征： 在中新世中晚期至早更新世末期， 青藏高原北、东边缘主要受来自印度板块碰撞青藏块体产生的垂直块体边界方向的挤压， 在高原周缘主要形成逆断裂． 构造应力场以逆断型为主； 早更新世末期以后，印度板块继续向北推挤， 高原内部挤压变形增大． 与此同时， 在高原东侧边缘形成北西－南东方向的引张， 构成了高原东部块体向东、南东方向滑移的有利条件， 从而导致了高原周边一系列断层由逆冲改变为走滑， 构造应力场以走滑型为主． 其最大主压应力方向相对早期构造应力场发生了一个顺时针方向的旋转．
The Quaternary tectonic stress field determined by fault slip data and the crustal deformation analysis results since the Late Tertiary can well explain the crustal dynamics evolution characteristics of the northern and eastern edges of the Tibetan Plateau since the middle and later stages of the Miocene: The middle and late Miocene to early Early Pleistocene, the northern and eastern edges of the Tibetan Plateau are mainly squeezed in the direction perpendicular to the boundary of the block caused by the collision of the Indian plate with the Qinghai-Tibet block, and mainly formed in the periphery of the plateau. The tectonic stress field is dominated by reverse faulting. After the end of the Early Pleistocene, the Indian plate continued to push northwards, and the compression deformation inside the plateau increased. At the same time, the extension of the NW-SE direction at the east edge of the plateau formed favorable conditions for eastward and southeastward sliding of the eastern plateau, resulting in a series of faults around the plateau that changed from thrusting to The slippery, tectonic stress field is dominated by the slippery type. The direction of maximum principal compressive stress has a clockwise rotation relative to the early tectonic stress field.
