Abstract:   (6683 Views)

This paper presents a description of the equipment, testing procedure, and methodology to obtain ground

mechanical parameters. The p-y curves for laterally loaded piles are developed. Methods for the development of p-y

curves from pressure meter and dilatometer (DMT) test are described. P-y curves are used in the analysis to represent

lateral soil-pile interaction. The pressure meter offers an almost ideal in-situ modeling tool for determining directly

the p-y curves for the design of deep foundations. As the pressure meter can be driven into the soil, the results can be

used to model a displacement pile. DMT tests were performed for comparisons with PPMT tests. Correlations were

developed between the PPMT and DMT results, indicating a consistency in soil parameters values. Comparisons

between PPMT and DMT p-y curves were developed based on the ultimate soil resistance, the slope of the initial

portion of the curves, and the shape of the curves. The initial slope shows a good agreement between PPMT and DMT

results. The predicted DMT and PPMT ultimate loads are not similar, while the predicted PPMT and DMT deflections

within the elastic range are identical.
