Judgement of Frost Heaving of Rocks by Freezing Test

open access: yesJournal of the Japan Society of Engineering Geology, 1986
There are some tunnels which have been deformed by frost heaving of rock behind the lining. We already reported about the common features in mode and progress of their deformations. This paper describes the geological conditions of frost heaving rocks which were detected in freezing test of rocks.

New semi-analytical approach for ice lens heaving during artificial freezing of fine-grained material

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
The calculation of frost heaving with ice lens formation is still not standard for construction projects using artificial ground freezing (AGF). In fine-grained material, ice lenses may initiate and lead to significant heaving at the ground surface ...

Development of frost heave test [PDF]

open access: yes, 2010
Frost heave tests conducted in laboratory conditions are very sensitive to the testing arrangements in which they are executed. There are numerous protocols in different countries but an internationally acknowledged procedure for frost heave test has not

Modelling frost heave in unsaturated coarse-grained soils

open access: yes, 2021
© 2020, Springer-Verlag GmbH Germany, part of Springer Nature. Coarse-grained soils were considered not susceptible to frost heave. However, substantial frost heave has been observed in unsaturated coarse fills in high-speed railway embankments.

Experimental and Modeling of Residual Deformation of Soil–Rock Mixture under Freeze–Thaw Cycles

open access: yesApplied Sciences, 2022
Projects in seasonal frozen soil areas are often faced with frost heaving and thawing subsidence failure, and the foundation fill of most projects is a mixture of soil and rock. Therefore, taking soil–rock mixture with different rock contents as research

Experimental Study on Freezing Mode to Reduce Frost Heave

open access: yes, 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 jacking characteristics of steel pipe screw piles for photovoltaic support foundations in high-latitude and low-altitude regions

open access: yesSoils and Foundations, 2023
In this study, the frost jacking characteristics of steel pipe screw piles for photovoltaic support foundations in high-latitude and low-altitude regions are studied via in situ tests and numerical simulations.

Study on Frost Heaving Characteristics of Sulfate-Bearing Sand in Seasonally Frozen Regions

open access: yesApplied Sciences
With the Longzhong Water Conservation and Ecological Water Supply and Storage Reservoir Project (Upper Yellow River) as the engineering background, this study selected sulfate sandy soil from Jingtai County (Baiyin City, Gansu Province, the project area)

Study on the Influence of Initial Water Content on One-Dimensional Freezing Process of the Qinghai-Tibet Silty Clay by Using Digital Image Technology

open access: yesGeofluids, 2022
The water content of the foundation soil will change dynamically as a result of rainfall, snowfall, and ground surface evaporation, leading to a significant change in frost heave properties of the foundation soil in cold regions. One-dimensional freezing

Coupled thermo-hydro-mechanical modeling of frost heave and water migration during artificial freezing of soils for mineshaft sinking

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2022
Artificial freezing of water-bearing soil layers composing a sedimentary deposit can induce frost heave and water migration that affect the natural stress–strain state of the soil layers and freezing process.
