Journal of Rock Mechanics and Geotechnical EngineeringFrost heave in water-bearing rock masses poses significant threats to geotechnical engineering. This paper developed a novel three-dimensional (3D) frost model, based on the combined finite-discrete element method (FDEM), to investigate the frost heave ...

Analytical prediction of frost heave forces against sheet pile walls
, 2023 I kalla klimat kan stödkonstruktioner utsättas för lastökningar till följd av tjälande jord. Tjälen bildas när vattnet i jorden fryser, och leder ofta till en volymexpansion i marken.

Frost heaving forces in Leda Clay
Canadian Geotechnical Journal, 1970 The frost heaving forces developed under a 1 ft (30.5 cm) diameter steel plate were measured in the field throughout one winter. The steel plate was fixed at the ground surface with a rock-anchored reaction frame. Heave gauges and thermocouples were installed at various depths to determine the position and temperature of the active heaving zone.The ...

Challenges in Numerical Simulation of Frost Heave
Frost heave of soil extensively exists in northern regions and poses a significant threat to infrastructure in cold regions. Despite over a century of research, challenges persist in numerically simulating frost heave. This study addresses two key issues:

Modeling of frost depth and frost heave in the Luoma test site [PDF]
, 2013 Construction work in Finland is a year-round operation, regardless of the challenges that the cold Finnish winter presents. Finland is located in a region where frost effects must always be taken into consideration as a part of designing and construction

Assessment of Frost Depth and Frost Heave in Romania
Applied SciencesThe investigation of extreme weather and climate events has gained momentum in the last few decades, spurred in part by political involvement. However, not enough attention has been paid to the historical recorded data of climate monitoring. An accurate estimate of maximum soil frost depth is an important factor in determining construction costs and ...

Frost Heave of Irrigation Canals in Seasonal Frozen Regions
, 2019 Soil frost heave acts as a driver of the emerged fracture in the concrete lining of irrigation canals and subsequent water leakage in seasonal frozen ground. A model test was carried out on the frost heave of a U-shaped canal with concrete lining.
