Seismic Slope Stability Analysis by Considering Tension Crack

  • Chapter
  • First Online:
Earthquake-Induced Landslides

Part of the book series: Springer Natural Hazards ((SPRINGERNAT))

Abstract

This chapter proposes an approach for how to consider tension failure in addition to shear failure in widely used FLAC3D, a finite difference method, so that stability analysis can also be carried out for a slope with a complex slip surface. It is shown that the safety factors estimated using the numerical methods are almost the same comparing to an analytical method for a homogeneous slope. Additionally, it is shown by a large number of analysis examples that the effect of tension failure on slope stability is significant and the safety factor will be incorrect if tensile failure is ignored in the case of seismic loading.
