In order to estimate the negative friction of pile, the experiments on two kinds of model pile were performed using the consolidation test apparatus. Fig. 2 and Fig. 3 show the experimental apparatus. The model piles are a polyvinyl chloride pipe and a mortar bar, 3.2cm in diameter. The relations between negative friction and consolidation stress are obtained by measurement of the point resistance. From these results, we obtain the fact that the application of Broms's equation for the calculation of the negative friction is most adcquate.
