...H. A. Amundsen; A. Emdal; V. Thakur A new method for storing mini-block samples was developed by the Norwegian University of Science and Technology. The method consists of storing samples inside a pressurised storage cell (PSC) in order to minimise the effects of stress relief. The pilot study...

...F. Molina-Gómez; C. Ferreira; C. Ramos; A. Viana da Fonseca Obtaining undisturbed high-quality samples is a challenge in geotechnical engineering since soils may present significant volume changes and collapse in its structure during sampling or handling at the laboratory. Nowadays...

...G. T. Lim; J. A. Pineda; N. Boukpeti; A. Fourie; J. A. H. Carraro A small-scale physical modelling program using particle image velocimetry and digital image correlation techniques was designed to obtain a refined understanding of the disturbance experienced by calcareous silt during tube sampling...

...H. A. Amundsen; J. Jønland; A. Emdal; V. Thakur A soil sample goes through stress changes during and after sampling. Sensitive clays are affected by sample disturbance and stress changes have a great effect on the quality. The reduction of in-situ total stresses to zero causes the soil sample...

...E. D. Hover; Q. Ni; I. Guymer A small-scale physical modelling system was developed and employed to investigate the effects of tube sampling. Amorphous silica and an oil blend of matching refractive index were mixed to form a transparent soil, and black glass beads were embedded within the soil...
