Secondary Frost Heave in Freezing Soils [PDF]

open access: yesSIAM Journal on Applied Mathematics, 1989
Summary: A mathematical model of secondary frost heave in freezing, gravelly soils is presented. This model is due to \textit{K. O'Neill} and \textit{R. D. Miller} [Water. Resour. Res., 21, 281-296 (1985)], who sought numerical solutions. Here, their model is made nondimensional and is analyzed using asymptotic analysis.

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.

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
