Abstract

The paper presents the results of static tension load tests performed on four closed-ended and one open-ended pile installed at a soft Clay test bed site. The piles sizes ranged from 4m long, 73mm circular steel piles, to 6m long, 250mm square concrete piles. The paper compares the average shaft resistance measured after full and partial equalisation of excess pore pressures set-up during installation, and considers the effect of installation mode, pile type and pile end condition (open or closed ended) on the piles shaft resistance. A number of design approaches from the literature were used to estimate the capacity of the piles at the site. The performance of these is briefly discussed.
