【摘要】 利用断层滑动方向资料反演构造应力张量的分期计算方法，获得鲜水河断裂带区域第四纪以来两期主要构造应力作用：第１期为早～中更新世，构造应力作用以北东－南西向挤压为特征；第Ⅱ期自晚更新世至今，构造应力作用以近东西向挤压和近南北向拉张为特征。更多还原

【Abstract】 By use of fault slip data in invesion of using different-stage tectonic stress tensors，we haveobtained two stages of tectonic Quaternary stress field of the Xianshuihe fault zone. In the firststage（from early-mid Pleistocene ），the tectonic stress field is characteristic of NE-SW compres-sion. In the second phase（from late-Pleistocene to the present），the tectonic stress field is main-ly characteristic of nearly E-W compression and nearly S-N extension. In this stress field，the Xi-anshuihe fault mainly shows a left-lateral slip.更多还原
