| 摘 要： | 采用弹塑性有限元分析，探讨了地下采动引起斜坡应力场和位移场的变化规律，提出了采动条件下斜坡变形机制的地质模式。结果表明：采动条件下的斜坡变形、地形条件和介质条件起主要作用，采动引起软弱夹层上、下岩层的相对滑移，对斜坡的稳定性影响极大

| Abstract: | The change law of stress field and displacement field of declivity caused by underground mining movement is investigated with the elastoplasticfiniteelement analysis,and the geologic model of deformation mechanism of declivity under mining movement is put forward.It is shown that the deformation of declivity and the conditions of topography and medium play a main role.The relative slip between the upper and lower strata of the loose and weak intercalation under mining movement has great influence on the stability of declivity. |
