Interpretation of stress measurements made around closed-ended displacement piles in sand

An interpretation is given of instrumented calibration chamber experiments involving comprehensive measurements of the stresses developed on and around closed-ended model displacement piles installed in pressurised silica sand. Conclusions are drawn regarding the mechanisms and stress regimes that apply during and after penetration, and how these compare with cavity expansion treatments and other analyses. The experimental arrangements and measurement details are described fully in a companion paper.
