Numerical Analysis of Dynamic Evolution Characteristics of a Large Rock Landslide in Tangjiashan

Figure 11

Schematic diagram of pull-apart landslide damage [28]. (a) Severe seismic forces have caused tension cracks in the shoulders of slopes. (b) As the tension cracks expand, debris from the top of the slope rolls into them. (c) Further extension of tension cracks and accumulation of deformation energy in the locking section. (d) The locking section is sheared off, the slope is unstable and the landslide is initiated.
