- Description
- This paper analyses the effects of tube sampling in soft clay with particular emphasis on the modifications that occur in the clay fabric for tube specimens retrieved using open samplers (Shelby) as well as a fixed-piston sampler relative to a Sherbrooke block sampler. Tube specimens of an estuarine soft clay are analysed in this study. Mercury intrusion porosimetry (MIP) tests are carried out to infer the pore size density function (PSD) of specimens trimmed at different locations along the tube and these are compared against those performed on undisturbed clay, obtained from Sherbrooke specimens, to estimate variations in the natural soil fabric due to tube sampling.
