摘　　要：受2003年7月13日千将坪滑坡的影响,位于其北东侧牵引区的千将坪东滑坡大范围出现了因拉张和剪切作用形成的裂隙。本文研究了因滑坡联动作用而形成的牵引区特征,对千将坪滑坡发生时在千将坪东滑坡体上所产生的裂隙形成作用方式进行了研究,并分析了千将坪滑坡体不同部位在滑坡滑动过程中的相互牵引与影响方式。通过研究分析,将滑坡滑动时的牵引方式简单分为以拉张卸荷为主和以边界剪切为主的两种模式,并以这两种牵引模式来分析白果树滑坡群中各个滑坡之间的相互制约关系,拟通过从滑坡联动作用阐述千将坪滑坡以东白果树滑坡群的整体稳定及局部失稳对滑坡群整体稳定性的影响。The Eastern Qianjiangping landslide is come into being large-scale fracturing,tensile and shear cracks under the influence of Qianjiangping landslide which is active on July 13,2003.This paper deals with the characteristics of the traction area,carry out a simple analysis to the formation of cracks of the Eastern Qianjiangping landslide and the Interaction of the different parts of the Qianjiangping landslide.Based on the above analysis,the traction methods will be simple divided into extensional unloading dominated and shear dominated of the boundary.Finally,land-linked modes are used to analyze the influence of the integral stability or local instability of Baiguoshu slide group on the active possibility of all slides in this area.
