Influence of the Slope Shape on Seismic Stability of a Slope

Abstract

The slope shape is one of the most intuitive factors affecting the seismic stability of a slope. However, current research on this subject is mainly focused on statistical analysis and seismic response law, and the influence on seismic stability evaluation of the slope is rarely discussed. Furthermore, slope shapes are often simplified for easy numerical model building. In view of this, five slope models with different slope shapes are considered, and the time-history analysis method and Newmark method are chosen to evaluate the seismic stability of these slope models under different amplitudes. The purpose of this paper is to compare the seismic stability of slopes with different slope shapes and to study the feasibility of simplifying the slope shape when evaluating the seismic stability of a slope.

Slope Deformation Mechanisms and Stability Assessment under Varied Conditions in an Iron Mine Waste Dump

“…The results revealed that the effect of intermediate principal stress on the slope stability in the presence of the joint flow and non-joint flow conditions was equivalent. Zhang et al [24] considered five slope models with different slope shapes and performed the time-history analysis based on the Newmark scheme to assess the seismic stability of the established slope models with various amplitudes. The results indicated that the orders of seismic stability of slopes with different shapes subjected to identical amplitudes were almost broken line slope, concave slope, linear slope, broken line slope, and convex slope from high to low.…”
