中文摘要：

马达岭滑坡是典型的采矿诱发型滑坡,自然斜坡为平缓反倾层状结构。以马达岭滑坡为原型,采用物理模拟方法,研究两层开采条件下采动斜坡的变形过程,并分析该类斜坡变形破坏的地质力学模式。研究表明：煤层开采后采空区边界上覆岩体产生应力集中,导致采动裂隙首先产生于该部位,以陡倾竖向倾倒式裂隙为主,裂隙向采空区中部扩展并逐渐形成离层裂隙和剪切裂隙;变形稳定后采空区上覆岩层弯曲,在地表形成沉陷区;受采空区上覆岩层沉陷的推挤作用,外侧坡体沿煤层向坡外滑移,导致坡体下部隆起。该类斜坡变形破坏的地质力学模式可以分为：弯曲–拉裂（＂表生＂改造阶段）、塑流–拉裂、蠕滑–拉裂3个阶段。

英文摘要：

Madaling landslide is a typical mining induced landslide,of which the natural slope is a gently counterinclined layered structure. In this paper,the physical modeling method was used to study the deformation process of the mining slope under the two layer mining condition and the geomechanical mode of the slope deformation was analyzed. After the coal mining,the stress concentration occurs in the overlying rock of goaf boundary leading to rock cracking initially mainly in the vertical direction. The mining fissures expand to the centre of goaf and gradually form the abscission fissures and shear fissures. After the deformation becomes stable,the overlying rock strata of goaf were bended to form a subsidence area on the surface. Due to the pushing of goaf overburden subsidence,the outer slope slides along the coal seam resulting in the uplift of the lower part of the slope. The geo-mechanical model of this kind slope deformation and failure can be divided into the bending-tensile（＂supergene＂ transformation stage）,plastic flow-tensile and creep-tensile three stages.
