Abstract With global warming, thaw-induced landslides occur more frequently in permafrost, which not only
threaten the safety of infrastructures as general geohazards but also worsen global warming due to carbon
release. This work presents a novel computational framework to model thaw-induced landslides from a
multiscale perspective. The proposed approach can capture the thermal-mechanical (TM) response of
frozen soils at the particulate scale by using discrete element method (DEM). The micromechanics-based
TM model is superior to capturing the sudden crash of soil skeletons caused by thaw-induced cementation
loss between soil grains. The DEM-simulated TM response is then homogenized and directly fed into… More >
