| Abstract: | Based on the engineering geological investigation, the deformation of the K28 slope was simulated with discrete element method under natural and saturated state. The deformation failure mechanism of this low dip angle consequent slope was analyzed. That is slipping and cracking under compression.The mechanism that groundwater accelerates deformation failure of the slope was elucidated. Finally this paper gives some reasonable advices for engineering control design. |
