T1 - Geotechnical and geophysical characterization of a pile test site in post-glacial soil N2 - Two research institutes are currently evaluating dynamic pile load testing methods on bored piles in a sandy environment. A test site has been prepared, which ensures comparable conditions at all pile locations and provides detailed knowledge on soil and other boundary conditions. A detailed site investigation program was performed at a dedicated area on the BAM test site south of Berlin, Germany. Undisturbed soil samples have been collected from boreholes. In addition several CPTs and geophysical surveys have been performed. The site consists mainly of well graded, partly well compacted medium sands. But at depth an inhomogeneous gravel layer was detected in some parts of the site. This has led to a redesign of the test piles. They are now shorter than originally intended to avoid gravel layers at depth and to ensure that the drop weight available for dynamic test is capable to mobilize the required load.
