Numerical Investigation of Soil–Rock Mixture Landslide Runout by Random Field and Finite Elements
Publication: ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part A: Civil Engineering
Volume 10, Issue 2
Abstract
To explore the entire runout process of a soil–rock mixture (SRM) slope triggered by an earthquake, large deformation finite element (LDFE) analyses combing two-phase random media are conducted. The feasibility and reliability of the LDFE method used in the current study to simulate the landslide process are checked by comparing the shape after the landslide and the runout distance with the results of the previous study; then, a two-phase random medium is incorporated into the finite element model to mimic the SRM slope. Monte Carlo simulation is performed to calculate the runout distance of the SRM slope considering the random distribution of rock, and the effect of rock volume fraction and horizontal peak acceleration is revealed by conducting probabilistic analyses. The findings of this research might facilitate the risk assessment of SRM landslides.
