Experimental Research on Frost Heave Characteristics of Gravel Soil and Multifactor Regression Prediction

Advances in Materials Science and Engineering, 2018
Gravel soil is usually considered to be insensitive to frost heave. However, many frost heave deformations of foundation in seasonal frozen region indicate that gravel soil may also produce frost heave under certain special conditions. In order to gain a

Experimental and analytical investigation on frost heave characteristics of coarse-grained soils under closed and open systems

Frontiers in Earth Science, 2022
Coarse-grained soil is widely used in the seasonal frozen soil region as subgrade filler. However, substantial frost heave has been observed in coarse filler in high-speed railway embankments.

A Generalized Secondary Frost Heave Model

SIAM Journal on Applied Mathematics, 1994
A generalized model for secondary frost heave is developed. Secondary frost heave arises during freezing owing to cryostatic suction effects that can increase the upward water permeation to facilitate ice-lens growth and increased heave. Nondimensionalization and scaling are used to simplify the model equations and to identify a dimensionless group ...

Anisotropic frost heaving coefficient of saturated permafrost considering moisture migration process based on standards

Shuiwen dizhi gongcheng dizhi
Frost heave in positive permafrost is a critical factor leading to frost damage of engineering in the cold region. The frost heave process results from the dynamic interaction of hydro-thermal forces.

Numerical Analysis of Frost Heave and Thaw Settlement for Pipeline Buried in Frost-Susceptible Soil via Thermosiphons

Applied Sciences, 2023
Seasonal frost or permafrost soils may encounter frost heave or thaw settlement resulting from atmospheric temperature changes and/or heat emanating from the resource-carrying pipeline. Notably, these soil movements can damage the pipeline. Thus, various

Lime stabilisation for earthworks: a UK perspective [PDF]

, 2014
Lime stabilisation is a versatile technique applied during earthworks operations. Modern soil recycling units are much more efficient at pulverising fill material and intermixing the added binder/water than machinery available 20 years ago.

Experimental and Theoretical Determination of the Frost-Heave Cracking Law and the Crack Propagation Criterion of Slab Track with Water in the Crack

Applied Sciences, 2019
Crack propagation produced by frost heave affects the durability of slab-track structures in high-humidity and cold regions in China. This work is intended to reveal the evolution laws of frost-heave crack propagation, establish evaluation criteria for ...
