dc.description.abstract | The Jiufengershan rock-and-soil avalanche is one of the largest landslides triggered by the Chi-Chi Taiwan earthquake (September 21, 1999). In order to study landslide triggering and propagation by seismic shaking, we propose a method that combines features of the classic Newmark approach with mechanical relations involving Mohr-Coulomb failure criteria, porewater pressure and shear heating during the sliding process. The effective shear strength is affected by shear heating and by pore-pressure variations during the sliding process. The shaking process was simulated using strong-motion accelerograms of the three nearest free-field stations, which surrounded the landslide. The initiation and propagation of earthquake-induced landslides are mainly controlled by the peak and residual shear strengths, respectively. The increase in temperature in the shear zone increases the pore-water pressure and weakens the shear strength. Rock avalanches are generated when mechanical parameters achieve critical threshold values, such that the residual shear strength is less than the tangential projection of body forces. | en |
