Abstract

The reasonable selection of parameters will be of great significance for earthquake landslide assessment. To study the correlation between the ground motion parameters and slope seismic response, 100 records of actual ground motion with different characteristics were selected, and each of the ground motions’ peak ground acceleration (PGA), peak ground velocity (PGV), peak ground displacement (PGD), effective peak acceleration (EPA), arias intensity (AI), cumulative absolute velocity (CAV), duration, and characteristic period were taken into account. Moreover, a two-dimensional finite element model of soil slope was established; the deformation and stress response of the slope under each ground motion condition were simulated. The influence law of the ground motion parameters on soil slope seismic response has been revealed, with the correlation between the ground motion parameters and the soil slope seismic response being reflected. The results can provide a theoretical basis for selecting the ground motion parameter indexes in the soil slope seismic analysis and the hazard evaluation of earthquake-induced landslide (EQIL).
