Abstract:

A series of instrumented jacked model pile tests and another series of uninstrumented grouted model pile tests in a cemented calcareous sand were performed. The influence of pile installation method, degree of sand cementation and pile type on the static behavior are presented and discussed. The pile behavior was reproduced using a non-linear strain-softening pile-soil interface model in a simplified boundary element analysis. Theoretical predictions were also made of the behavior of piles in a number of field tests, using soil parameters derived from the model test data and also from some recent design recommendations.
