Dynamic response of saturated frozen soil foundation under underlying bedrock to harmonic load

Chen Huaiyuan, Ma Qiang

Journal of Theoretical and Applied Mechanics

2024

Vol. 62 nr 4

667--681

This study aims to provide a theoretical basis for engineering construction in alpine frozen soil area, simplify the soil medium of the site in alpine permafrost region to saturated permafrost, and expand the elastic foundation and saturated ground foundation to better reflect the dynamic response problem of permafrost site in alpine region. Based on the theory of solid porous media with pores, a physical model of dynamic response of saturated frozen soil foundation with underlying bedrock under vertical harmonic load is established, and the effects of temperature, porosity, cementation parameters, load frequency and contact parameters on the dynamic response are analyzed.
