文摘1 Introduction In recent years the thermomechanical behavior of soils has attracted more attention due to an increasing number of geotechnical practices involving thermal effects (Bourne-Webb et al,2013;Olgun et al.,2014;Loria et al,2018;Peng et al.,2018;Pinyol et al.,2018;Kaddouri et al.,2019;Mu et al.,2019).
