Determining frost heave classification by using ratio of frost heave to square root of time

open access: yesYantu gongcheng xuebao, 2023
The frost heave classification is the critical index for the design of foundation engineering in cold regions. At present, it is considered as a basic property of materials. Many criteria belong to empirical or semi-empirical methods and lack theoretical

Experimental Study on Freezing Mode to Reduce Frost Heave

open access: yesBuildings, 2022
Frost heave is an important factor affecting the safety and practicability of buildings in cold regions or artificial freezing engineering. In order to reduce frost heave, frost-susceptible silty clay was used in a one-dimensional frost heave testing ...

Frost heave [PDF]

open access: yesJournal of Glaciology, 2010
AbstractThe deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence ...

Frost Heave in Colloidal Soils [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2011
We develop a mathematical model of frost heave in colloidal soils. The theory accounts for heave and consolidation while not requiring a frozen fringe assumption. Two solidification regimes occur: a compaction regime in which the soil consolidates to accommodate the ice lenses, and a heave regime during which liquid is sucked into the consolidated soil

Effect of Anionic Polyacrylamide Polymer on Frost Heave Mitigation and Its Implication for Frost-Susceptible Soil. [PDF]

open access: yesPolymers (Basel), 2023
Seasonally frozen ground regions occupy approximately 55% of the exposed land surface in the Northern Hemisphere, and frost heave is the common global problem in seasonally frozen soil areas.

Frost heave behavior of coarse-grained materials for high-speed railways subgrade: experimental analysis and machine learning predictive modeling [PDF]

open access: yesScientific Reports
Coarse-grained subgrade fill has traditionally been considered frost-heave-insensitive. However, uneven frost heave in such materials has become a critical constraint for high-speed railways (HSRs) in cold regions.

Mechanistic analysis of frost heave in airport runway subgrades in seasonal frost regions and pavement structural tolerance thresholds [PDF]

open access: yesScientific Reports
This study addresses the structural damage of airport pavements caused by uneven frost heave in seasonal frozen soil regions. A three-dimensional finite element model based on elastic layered system theory was established to simulate pavement mechanical ...

Study on anti-frost heave effect of new thermal insulation subgrade of highway in seasonally frozen soil regions. [PDF]

open access: yesPLoS ONE
Frost heave is one of the important factors affecting the long-term stability and safe operation of subgrade in seasonally frozen soil regions. To investigate the anti-frost heave effect of foam concrete insulation and composite insulation structure ...
