COMPARISON BETWEEN THE RESULTS OF A PILE LOADING TEST AND CALCULATIONS BASED ON SOIL INVESTIGATIONS

The foundation of an overpass had been designed on prefabricated driven friction piles. The first pile installed, however, did not seem able to carry the design load, according to the driving formulae; so a loading test was proposed. Meanwhile a further soil investigation was carried out in the vicinity of this particular pile in order to check the preliminary results. Loading and unloading curves show that the design load value was on the safe side. Loads calculated from penetrometer and pressuremeter tests agree with the working loads derived from this diagram by the usual rules. Futhermore, there is a very good agreement between the observed settlement curve and the one calculated by the pressuremeter method. This study provides a check on the methods of calculation which can be used by the soil engineer in similar soil conditions. Small discrepancies as well as good agreement are pointed out according to the type of in-situ testing used. Once again it is shown that pile driving formulae have no practical use for determining the bearing capacity of friction piles.
