Secondary frost heave in freezing soils [PDF]
, 1996 Frost heave describes the phenomenon whereby soil freezing causes upwards surface motion due to the action of capillary suction imbibing water from the unfrozen region below. The expansion of water on freezing is a small part of the overall surface heave

Basic Study on the Frost Heave Pressure of Rocks : Dependence of the Maximum Frost Heave Pressure on Temperature [PDF]
, 2011 In this study, we attempted to measure frost heave pressure, i.e., the pressure that develops in the heat-flow direction when rocks are subject to frost heave and ice lenses grow.

Experimental study on frost heave in unsaturated coarse-grained soil caused by vapour transfer
Yantu gongcheng xuebao, 2021 The frost heave caused by vapour transfer has recently attracted much attention, but there is little experimental evidence so far. A series of laboratory experiments are carried out by using the newly developed frost heave apparatus.

Incidents of damage to berm drainage ditches in cold region and countermeasures [PDF]
MATEC Web of Conferences, 2019 Berm drainage ditches may fail due to frost heave in cold and snowy areas like Hokkaido. Many of these failures are regarded to be caused by damage due to frost heave in the ground or freeze-thaw, but no sufficient measures are being taken, as ...

Experimental study on delamination frost heave of steel fiber-improved soil
Yantu gongcheng xuebao, 2023 The segregation frost heave caused by water migration is the main source of frost heave, and the water migration law is the key factor to reveal the mechanism of frost heave of soils in the freezing process.
