Landslide Failure Mechanisms of Dispersive Soil Slopes in Seasonally Frozen Regions

Analysis of Rainfall-Induced Landslide on Unsaturated Soil Slopes

This paper investigates rainfall-induced landslides on partially saturated soil slopes using the 2011 Umyeonsan landslides at the center of Seoul, Korea. An integrated analysis of rainfall-induced landslide was carried out through laboratory tests, field tests, and numerical analysis. The results of comprehensive investigations in the Umyeonsan region demonstrate that landslide activity is clos...

Dissipation of Antimicrobials in a Seasonally Frozen Soil after Beef Cattle Manure Application.

Land application of manure containing antimicrobials results in the dispersion of the antimicrobials in agro-ecosystems. Dissipation of excreted antimicrobials in seasonally frozen agricultural soils has not been fully characterized under field conditions. This study investigated the field dissipation kinetics of chlortetracycline, sulfamethazine, and tylosin over a 10-mo period after fall appl...

Shear Band and Landslide Dynamics in Submerged and Subaerial Slopes

Simulated and In Situ Frost Heave in Seasonally Frozen Soil from a Cold Temperate Broad-Leaved Korean Pine Forest Short Title: Frost Heave in Seasonally Frozen Soil from a Temperate Forest

Frost heave, which is the volumetric expansion of frozen soil, has great ecological significance, since it creates water storage spaces in soils at the beginning of the growing season in cold temperate forests. To understand the characteristics of frost heave in seasonally frozen soil and the factors that impact its extent, we investigated the frost heave rates of forest soil from different dep...

Modelling of cryogenic processes in permafrost and seasonally frozen soils

This paper investigates the thermo-hydro-mechanical (THM) behaviour of soils subjected to seasonal temperature variations in both permafrost and seasonally frozen conditions. Numerical modelling of soil freezing and ice segregation processes is presented, and compared against small-scale physical modelling experiments. The coupled THM model presented, which is solved by way of a transient finit...
