Investigation of compressional creep of clay soil with consideration of temperature effects

Transient dynamics of the thermally induced deformation of sands

“…For fine-grained soils (e.g., clay and silt), a decrease in the preconsolidation pressure [2][3][4] and an increase in the coefficients of primary consolidation 5,6 and secondary compression 7,8 have been observed within the temperature range of 20 • C-100 • C. These changes in properties have been somewhat satisfactorily employed to explain the thermally induced deformation of such materials observed experimentally. [9][10][11][12][13][14][15][16][17] For coarse-grained soils (e.g., sand), thermal expansion of individual grains, which alters the contact force network and causes grain rearrangement, has been considered responsible for the thermally induced deformation of such materials within the same temperature range.…”

These changes in properties have been somewhat satisfactorily employed to explain the thermally induced deformation of such materials observed experimentally 9–17 .…”
