INFORMAL DISCUSSION
Session 2
Laboratory and In Situ Techniques and their Interpretation
CHAIR: DR DAVID NASH AND DR SARAH STALLEBRASS
Points for discussion:
1. How robust are determination of stiffness parameters,
both elastic and at intermediate strains?
2. Do drained laboratory tests have any value in
engineering practice?
3. How can we measure values of permeability which will
be useful in design?
Dr Matthew Coop, Imperial College London
In his introductory overview, David Nash raised a question
about interpretation of bender elements. At Imperial College
we use time domain and frequency domain techniques and
