Analysis of Dynamic Failure Process and Failure Mechanism of Rock Slope Under Earthquake
The impact and damage of earthquakes on slopes cannot be ignored.In this paper,the dynamic failure process of the rock slope,the acceleration amplification coefficient at the slope surface,the horizontal acceleration acceleration of the peak earthquake and the failure depth are studied by using the dynamic analysis module of FLAC3D as the power source,considering the influence of tensile failure on the failure of the rock slope.The results show that under the action of earthquake,the failure of rock slope is not a simple shear failure,but is caused by the tensile failure at the top of the slope and the shear failure at the foot of the slope gradually forming a penetrating surface,and the acceleration amplification coefficient of the top of the slope>the acceleration amplification coefficient of the middle of the slope surface>the acceleration amplification coefficient of the lower part of the slope surface show an obvious"whiplash effect",and the slope failure surface gradually deep-ens with the increase of the horizontal acceleration of the peak earthquake.
