Dynamic processes of anchored rock slope with discrete element method

The dynamic failure processes of a block of rock behind the powerhouse of a hydro-power plant was investigated using the universal distinct element code (UDEC),which is based on discrete element method (DEM),and the dynamic timehistory method.The result showed that the failure processes of rock slope without support can be divided into four stages:namely unsliding stage,slow sliding stage,accelerating stage and failure stage.That is to say the failure of rock slope under seismic load is a cumulative process.The axial force response curve of anchor showed a good correlation with the relative displacement of element around the anchor element,which indicated that the latter could be one of factors of the anchor reinforcement effects under earthquake.The optimal proposals for slope strengthening was suggested based on the cable axial force distribution pattern,and it could be used as a reference for the similar projects.
