Comparison of Geoacoustic Models for Unfrozen Water Content Estimation
Lyu, Chuangxin; Ghoreishian Amiri, Seyed Ali; Grimstad, Gustav; Høyland, Knut Vilhelm; Ingeman-Nielsen, Thomas (Peer reviewed; Journal article, 2020)This paper reviews eight geoacoustic models applied to frozen soils: crystal growth models (grain cementing, grain coating, matrix supporting, and pore filling), the weighted equation (WE) model, Zimmerman and King's model ... -
Estimation of the Unfrozen Water Content Based on a Joint Electrical and Acoustic Method
Mikalsen, Tonje Roås (Master thesis, 2020)Frossen jord består av ufrossent vann, is og jordmateriale. Innholdet av ufrossent vann reduserer jordens styrke og fører til økte setninger. I denne masteroppgaven evalueres en metode som bruker både elektrisk motstand ... -
Joint Acoustic and Electrical Measurements for Unfrozen Water Saturation Estimate—A Review
Lyu, Chuangxin; Ghoreishian Amiri, Seyed Ali; Gao, Hao; Ingeman-Nielsen, Thomas; Grimstad, Gustav (Chapter, 2019)The previous laboratory study of joint electrical resistivity and acoustic velocity measurements is reviewed for both consolidated and unconsolidated permafrost in this paper. The relation of logarithm of resistivity log(R) ... -

Parametric Study of Mechanical Properties for Saline Frozen Clay
Hovind, Morten; Lien, Kjetil (Master thesis, 2020)Frossen grunn er jord eller stein med temperatur under 0 °C og betegnes som et naturlig kompositt bestående av mineralkorn, is, vann og luft. Når jorden fryser, sementerer isen jordpartiklene sammen, noe som fører til økt ... -

Pore-water pressure development in a frozen saline clay under isotropic loading and undrained shearing
Lyu, Chuangxin; Nishimura, Satoshi; Ghoreishian Amiri, Seyed Ali; Zhu, Feng; Eiksund, Gudmund Reidar; Grimstad, Gustav (Peer reviewed; Journal article, 2021)A systematical testing program on frozen Onsøy clay under isotropic loading and undrained shearing at different temperatures (− 3 ~ − 10 °C), strain rates (0.2~5%/h) and initial Terzaghi effective stress (20~400 kPa) was ...
