Experimental modelling of end bearing piles in sand

The paper describes and analyzes the results of model pile tests which have been conducted for the purpose of simulating end bearing piles in sand. The tests involved the simulation of both a displacement pile installed by jacking and a bored pile installed by retrieving casing. The sand beds were prepared by the sand raining technique in a test chamber (B-2 type) of 1.0 m diameter and 1.6 m height. Different pressures have been applied on the surface of the sand bed to simulate the in-situ stresses at different depths. Sensitive pressure cells mounted on the bottom and circumferential area of the test chamber allowed for measuring soil pressures at these boundaries during the installation and testing of the model piles. The behavior of the model piles is investigated in terms of the unit point load, and the results are compared with field tests carried out in similar stress levels and soil condition.
