Sample disturbance effects in the laminated facies at the Bothkennar soft clay research
site are examined by comparing the results of laboratory tests on specimens obtained
from three fixed piston tube samplers. A ...
Techniques required to successfully obtain downhole block samples of typical
very soft high plasticity organic clay from Ireland are described. The vane shear strength of
the material is as low as 4 kPa. These included ...
A comparative study of the NGI Direct Simple Shear Test (DSST) and the Mikasa Direct Shear Test (DST) is reported. Samples from Norwegian Drammen clay and Japanese Ariake clay were subjected to both types of test. An ...
Upland headwater streams are dynamic systems, responding rapidly to changes in climatic conditions. This study examined the effects of a catastrophic rainfall event, that occured on 24 October 2011 on the east coast of ...
A cost efficient way of investigating shallow sediments and for collecting soils data for many offshore geotechnical problems, e.g. anchoring of floating structures with suction piles or evaluation of submarine slope ...
Guidance is provided for geotechnical engineers designing civil engineering
works in silty soils based on a detailed characterisation of a glaciomarine silt from Os in western Norway. It was found that these soils are ...
Wave-based control (WBC) of underactuated,
flexible systems considers actuator motion as launching a mechanical wave into
the flexible system which it then absorbs on its return to the actuator. The launching
and absorbing ...
Geotechnical characteristics of Dublin Boulder Clay (DBC) based on detailed site
investigation and site experience from some recent large projects in Dublin are presented.
This paper attempts to synthesise available ...
It is well accepted that the quality of soft clay samples obtained using standard
fixed piston samplers can be relatively poor and that block samples are necessary to
yield very high quality samples. However for many ...
Devereux, Paul J.(University College Dublin. School of Economics, 2006-05)
In synthetic cohort models (cross-sectional data grouped at the cohort and year level), researchers often ignore potential biases induced by sampling error because they have 100 or 200 observations per group. I investigate ...
