Soil nailing is being used in many projects in glacial tills in Ireland, particularly to provide
temporary support to steep slopes. Little design guidance is available for such materials and it
is known that application ...
This paper discusses the design and development of a new direct simple shear (DSS)
apparatus for testing peat soils. The apparatus has been designed to test peat at low
effective stresses, representative of its in-situ ...
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 ...
The Multichannel Analysis of Surface Waves (MASW) technique, used
to determine shear wave velocity (Vs) and hence small strain stiffness (Gmax), has
recently generated considerable interest in the geophysics community. ...
A database of research quality CPTU and shear wave velocity
information for Norwegian marine clays has been assembled so as to study the small
strain stiffness relationships for these materials and to examine the potential ...
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 Discrete Particle Scheme (DPS) consisting of interacting circular particles is
utilised to examine the Multichannel Analysis of Surface Waves (MASW) technique.
Synthetic earth models of various complexity are generated ...
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 ...
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 ...
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 ...
