This paper includes a comparison between the measured data at the occasion of a campaign of full scale static pile load tests performed for the 3rd Bolivian International Conference on Deep Foundations and the values calculated by means of the software PIVER developed at IFSTTAR and using two kinds of t-z curves: The first one has been developed by Frank and Zhao (1982), and the second one is called AB1 (Abchir and al. 2016). These two kinds of t-z curves are defined by correlations from Ménard pressuremeter tests (PMT) data. The comparison between the measured and the calculated values enables to better estimate the bias and the uncertainty of the two t-z curves used and the method of the calculation of the bearing capacity.
