77th Meeting of the Transportation Research Board
January 1998 - Committee A2L02-Soil & Rock Properties
Call for Paper Synopses for Specialty Session on Local Strain Measurement in Laboratory Determination of Soil and Rock Stiffness.
At loading conditions insufficient to generate failure, soils and
rocks often exhibit high stiffnesses and commensurately small strains.
For many design conditions it is important that this low-strain behavior
is accurately assessed. Examples of particular importance are in the
assessment of the behavior of soil subjected to earthquake loading,
behind retaining walls (and hence the load-deformation response of
those walls), beneath pavements in response to traffic-induced loading
and around tunnels and other excavations.
In most laboratory tests, the behavior at the soil or rock boundary
is atypical of the whole specimen. For example, a triaxial specimen
is artificially constrained by the end platens. This upsets the stress
and hence strain field close to the loading point, leading to misleading
stiffness determinations. [see, for example, paper by John Burland on
"Small is Beautiful: The Stiffness of Soils at Small Strains" in the
Canadian Geotechnical Journal 26 (4), November 1989, 499-516.
Synopses (not more than 500 words long) of proposed papers should be by either email, fax, or regular mail to either Dr. Andrew Dawson or Prof. Paul W. Mayne not later than April 15th. Full papers will be invited in early May 1997 for those synopses offering contributions appropriate to the session's theme. Note that full papers have to be submitted to TRB for peer review, according to its normal procedures, by August 1st 1997.
It will be intended that the group of accepted papers will be published together as a Transportation Research Record, pending the TRB review process.
