A Method for Correcting Undrained Shear Strength for Sample Disturbance
TLDR
In this paper, a series of triaxial compression tests is performed on mixed soil samples having a wide range of plasticity index, and the pore pressure is measured for assessing the residual effective stress in the ideal, perfect and undisturbed samples respectively.About:

Interpretation of oedometer test data for natural clays
TL;DR: In this paper, two alternative approaches to the conventional e − log p method for determining yield stress are critically examined, and their advantages and limitations are identified; the yield stresses defined in both alternative approaches are also theoretically verified as identical for the oedometer test data.

A method for correcting consolidation parameters for sample disturbance using volumetric strain
TL;DR: In this article, the volumetric strain of an oedometer specimen, ev o, at in-situ effective overburden pressure, σv o′, determined from the 24-hour e − log σV′ curve, was investigated in terms of the sample disturbance, resulting from intentional sample disturbance in the laboratory.

The Behaviour of Saturated Clays During Sampling and Testing
Alec Westley Skempton,V. A. Sowa +1 more
TL;DR: In this article, it was shown that if two identical specimens of saturated clay are subjected to different changes in total stress without alteration in water content, and if the strains consequent upon these stress changes cause little alteration in micro-structure, then the undrained strengths of the two specimens will be practically identical.
