An integrated experimental-numerical frost heave prediction model

, 1993
Structural and geotechnical designs of some civil engineering structures require a prediction of potential frost heave. The present study is a novel approach which combines the experimental technique and numerical modelling to predict frost heave more ...

Pre-shutdown studies at the Calgary frost heave test facility

, 1986
The Calgary Frost Heave Test Facilit y, operational since 1974, is currently being run jointly by Foothills Pipeline and Energy, Mines and Resources Canada. The scientific and engineering purposes have largely been met in terms of the frost behaviour.

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:

Creep characteristics of sandstone during freezing/thawing process

Shuiwen dizhi gongcheng dizhi
The rock mass in cold regions is always subjected to the load and freeze-thaw. If the impact of long-term freeze-thaw mechanical behavior on sandstone mass is neglected, it would lead to significant hazards to the construction and safe operation of ...
