摘要

Ten soil samples were taken at various depths in a deep highway embankment at the site of the DB Culvert, a grossly under-designed, structural plate pipe, on Route 07-LA-210. These samples were subjected to unconsolidated-undrained, triaxial tests, and the data were analyzed using the Kondner-Duncan soil model, in which the stress-strain curves are approximated by regression hyperbolae. The report also discusses analyses of a low modulus inclusion (polyurethane foam) placed in contact with the periphery of the pipe in one of the test zones. Results of the analyses described in this report will be used in studies of soil structure interaction (e.g., by the finite element method), and this usage will be discussed in future interim reports pertinent to this project.
