Abstract: To reveal the deformation mechanism and evolution of potential diseases of the dumping site slope,a seriesof geo-mechanical model tests was conducted on the background of Yinwan Dumping site slope,Heidaigou open-pitmine. The process of dump slope elevating and groundwater infiltrating into loess basement was simulated. A method tosimulate dumping site above the water-saturated loess basement was introduced. During the tests,the influence of waterin loess basement was simulated by water injection from the holes on the bottom of the model. The variety of displace-ment of dumping site above the loess basement under filling,weak base,as well as water-saturated conditions was stud-ied. It shows that,as dump height increased,the main deformation transformed from the shear deformation above thewater-saturated loess basement to the vertical settlement above the natural loess basement,and the destruction of themodel was caused directly by the continually increasing of moisture content of the loess basement. The destructionmode trailing edge attachment the silty loess and the loess（puddles edge） overall sliding interface.
