Abstract: Based on the water–heat coupling model, this paper analyzes water migration laws and the change characteristics of the freeze–thaw interface under freeze–thaw cycles to determine the linkage migration range of the slope ...

Abstract: In this paper, a full vehicle–track–ground coupling model is presented to evaluate the dynamic response of the subgrade due to high-speed trains. The vehicle was modeled as a multibody. The track was considered as an Euler ...

Abstract: A thermo-hydro-mechanical (THM) coupling model that considers phase transition and frost heaving was developed for a diversion tunnel in a seasonally frozen region. Based on the partial differential equation defined by ...

Abstract: A track-unsaturated ground model was proposed to study the dynamic responses of the unsaturated subgrade induced by moving trainloads. The subgrade was modeled by an unsaturated poroelastic half-space, and the railway track ...

Abstract: Foam lightweight soil (FLS) has been widely used in geotechnical engineering because of their high strength, low density, and thermal insulation. However, few scholars have researched its application to subgrade engineering, ...
