Abstract
Strain rate effects have a significant impact on the behaviour of soils, and this has implications throughout geotechnical engineering, no more so than in the testing of deep foundations. In this paper, the results of a study using high speed triaxial testing on kaolin at strain rates from 1 %/hr to 180000 %/hr are
presented, and their implications for rapid load pile testing are set out. It is shown that both the soil strength and stiffness are rate dependent, and that the strength increases generally exceeded those expected. This study demonstrates that the damping co-efficients used in the analysis of rapid load pile tests can be derived from laboratory testing and that the relationship used can accurately model the rate dependent behaviour.
