The fundamental premise of this monograph is that transparent
synthetic materials with geotechnical properties similar to those
of natural soils can be used to study 3D deformation and flow
problems in natural soils. Transparent soils can be made by
matching the refractive index of synthetic soil materials and the
pore fluid. This monographs presents the geotechnical behaviour of
several families of transparent soils that can be combined to meet
model-test requirements, in terms of strength, deformation, or
permeability.
"Modelling with Transparent Soils" demonstrates how an optical
system consisting of a laser light, a CCD camera, a frame grabber,
and a PC can be used to measure spatial deformations in transparent
soil models non-intrusively. Transparent soil models are sliced
optically using a laser light sheet. A distinctive speckle pattern
is generated by the interaction of the laser light and transparent
soil. A 2D deformation field is obtained from two speckle images by
using an image processing technique named adaptive
cross-correlation, which is an advanced form of the digital image
cross-correlation (DIC) algorithm that utilizes both window sizing
and window shifting methods. The monograph demonstrates that
comparison of 2D deformation fields between transparent soil and
natural soil showed that the results were comparable in almost
every aspect. Three dimensional fields can be produced by combining
multiple 2D fields in Matlab.
Multiphase flow and surfactant flushing tests were also
simulated using a layered transparent soil systems and several
contaminants. The developed technology allows for visualizing the
contamination concentration and evaluating the performance of
remediation technologies in bench scale model tests.
