Dynamic failure mode and zoning of anti-inclined slope based on discrete element numerical simulation method
Under the action of earthquakes,once the instability and failure of the anti-inclined cutting slope are induced,it will bring immeasurable significant losses to the operational safety of highways.In order to further study the dynamic response characteristics of the anti-inclined slope,this paper used UDEC discrete element software to simulate the displacement process of the Scavia anti-inclined slope model under bidirectional seis-mic action,and analyzed the block motion mode.The results show that:(1)Under bidirectional seismic ac-tion,the motion state of each rock block in the anti inclined slope transitions from stable state to sliding out of the slope,and the closer the rock block is to the rear edge of the slope,the more intense the transition between the motion states of each rock block;(2)According to the motion state of the block,it can be divided into three regions.The rock block located at the front of the slope mainly undergoes a state change of"sliding,dumping,sliding-toppling",while the rock block in the middle of the slope transitions between sliding-toppling and sliding states,but the transition speed is relatively slow.The movement mode of the rock block at the rear edge of the slope is"sliding,toppling,sliding-toppling,sliding"state,where the sliding-toppling state transi-tions to the sliding state and the transition speed is fast.
