THM coupled model for simulating frost heave based on a new water film pressure criterion

open access: yesYantu gongcheng xuebao, 2023
The frost heave and thaw settlement are the main frost damage in cold areas, which are the complex coupling process of water, temperature and stress fields.

A Generalized Secondary Frost Heave Model

open access: yesSIAM 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 ...

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

open access: yesAdvances 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
