| 摘 要： | 选取川滇地区16个跨断层形变观测点，将断层两盘作为不变形的刚体分析断面相对滑动与断层两盘地表点位相对位移的定量关系，计算了各测点的水平扭动量、垂直位移量以及两者之间的比值，并分析了其与地震活动之间的关系。

| Abstract: | This paper choses 16 cross-fault deformation observation points in Sichuan-Yunnan region,for analyzing the quantitative relation between the relative sliding of fault plane and relative displacement of the sites on the two walls on ground surface and then calculates the amounts of horizontal twist,vertical displacement and the ratio between them,and analyzs the relation between the ratio and the earthquake activity simply. |

| Keywords: | Sichuan-Yunnan area earthquake fault activity cross-fault observation deformation |
