Abstract

Earthquakes are very likely to produce various geological disasters, and it is very important to study the stability and deformation characteristics of slopes under the action of earthquakes. In this paper, a three-dimensional numerical model of slope considering the structural section of rock body is established with an open slide slope as the research object, and the numerical simulation of seismic load is carried out for the slope based on the time-range analysis method. The results show that the steep slope responds to the seismic loading to a greater extent, and its displacement deformation is more obvious than that at the bottom of the rock body. The potential sliding surface formed by the slope is connected with the fault of the rock body, forming a more significant plastic through zone. With the increase of seismic load amplitude, the overall trend of PGA amplification coefficient is more obvious, showing the free surface amplification effect. With the increase of the slope height, the amplification effect has a certain attenuation trend.
