    Abstract

    The first part of this article deals with the determination of the critical depth Dc, below which the ground surface has little influence on the soil-structure interaction problem, and with the variation of soil resistance within that critical depth. A new approach is proposed to determine Dc using the relative rigidity of the pile with respect to the soil strength as measured by the pressuremeter limit pressure.

    The second part of the article summarizes seven pressurementer methods to predict the lateral behavior of piles. Predictions by four of the methods are compared with the results of a full-scale load test. All methods predict the measured behavior with reasonable accuracy suggesting that the pressuremeter provides a sound testing base for the behavior prediction of laterally loaded piles.
