Centrifuge Modeling of Earthquake-Induced Failure Process of Soil Slopes
To provide evidences for the aseismic evaluation of the soil mountain slopes of the Beijing Olympic Forest Park, the seismic response and failure process of mountain slopes during a strong earthquake were investigated using centrifuge shaking table model tests. The results showed that magnification factors and peak displacements of the slope increased with increasing altitude. The vertical displacement increased monotonically during shaking. The residue horizontal displacements pointed from the axis to both sides after the earthquake. The strain localization occurred mainly at the upper and middle of the slope and can lead to a final landslide. Water content has a significant effect on the strength and deformation modulus of the soil, and as a result significantly affects the aseismic stability level, magnification factors and deformations of the slopes.
