Effects of Temperature on Geotechnical Engineering

This Reprint presents recent advances in understanding the effects of temperature on geotechnical engineering. The collected studies address both the passive influence of temperature as an environmental or service condition and its active use as an engineering control measure. Topics include freeze-thaw damage in rocks and soils, high-temperature effects on rock strength and anisotropy, thermo-confining pressure coupling, the periodic thermal fatigue of salt rock, the temperature-dependent creep of dredged fill soil, artificial ground freezing, deep reservoir fracturing, geothermal system optimization, and thermo-hydro-mechanical coupling behavior in high geothermal tunnels. Together, these contributions demonstrate that temperature can significantly affect pore structure, crack evolution, strength, stiffness, deformation, permeability, and failure modes. The Reprint also highlights the importance of constitutive modeling, numerical simulation, field monitoring, and engineering optimization for improving the safety, durability, and sustainability of geotechnical systems under complex temperature environments.
