In order to study the effect of freezing and thawing liquid nitrogen on mechanical seepage characteristics coal rock with different water content values, conventional triaxial loading tests freeze–thawed samples values were carried out using non-contact digital image processing technology. The research results showed that same content, peak strength a sample was smaller than non-freeze–thawed s...

This article presents experimental results and analysis of change in freezing characteristics clays silts with pH moisture content the pore structures. The plastic non-plastic cold regions undergo significant changes thermal properties causing non-equilibrium conditions which can lead to frost-heave, thaw-weakening, thawing-induced landslides, mass wasting events. In geotechnical engineering, p...
