Molecular dynamics simulations were performed to investigate the properties of ice/quartz interface. The premelting liquid at interface, which behaves as a nanofluid, plays an important role in both compression and shearing processes. results reveal that sliding velocity, compression, temperature are crucial factors analyzing shear process interface quantifying stress. microscopic mechanisms underlying these effects closely tied formation evolution layer. Specifically, effect velocity shows logarithmic relationship between stress rate liquid, is attributed thinning behavior Compression affect thickening layer, leading decrease normal increases. Furthermore, when layer sufficiently thick, observed act direction opposite sliding. This study offers atomic-scale understanding connects findings tribological hydrodynamic theory.

Abstract On the basis of rock‐coupled joints Jiangluling Tunnel on G214 line in permafrost region Qinghai, a freeze‐shear test was carried out to study shear characteristics and failure mechanism jointed rock with different opening conditions. Given 3D shape parameters joint surface frozen shearing its were revealed building theory adhesion between ice layer. Results showed that comprised four stages, compaction, sustained deformation, yielding post‐peak stage. As tension grows from 7 mm 13 mm, reduction peak stress at pressures for each specimen ranges 43% 81%, cohesion is 79‐98%. The angle internal friction has no significant pattern roughness. Tests degrees three modes damage pressures.

ABSTRACT In high‐altitude mountain permafrost regions, the bedrock is commonly in a permanently frozen state with joints or fractures filled ice. An in‐depth understanding of temperature and strain rate‐dependent mechanical behavior urgently needed to deal rock slope hazards such regions. this study, uniaxial compression tests are carried out on ice‐sandwiched mass at different temperatures rates, failure process observed by acoustic emission (AE) system high‐speed camera. The results show that (1) shows strong dependency, as it decreases increasing following three‐stage trend. Two critical temperatures, −6°C −1°C, mark transition from brittle ductile back again. (2) There rate dependency well. strength increases first then increase rate, reaching maximum value 1 × 10 −3 s −1 . Meanwhile, mode exhibits transition. We propose concept ice‐rock interface cohesive zone (ICZ), which consists thin ice layer, their interface. bonding ICZ comes interlocking between pores cohesion mineral grains, thus being dependent. should originate ICZ.
