Book Description
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.

Book Description
Pile foundations in the offshore environment are frequently called upon to resist high horizontal load. Many pressuremeter methods have recently been developed to design piles, including techniques to formulate soil spring P-y curves directly from pressuremeter test results. Lateral soil resistance is now recognized to arise from two components: side shear and front resistance. The field measurement of mobilization rates and prediction of lateral side shear has never been made. This paper reports the attempts to measure lateral friction rates in sand and clay by employing torsion testing as a "yardstick" method. Pure lateral shears are mobilized and the effects of depth and installation method can be studied qualatively. It is suggested that since the soil shear modulus, G, is the controlling variable, the pressuremeter is a suitable insitu tool to duplicate pile installation disturbance and predict side shear mobilization rates.

Book Description
The pressuremeter is ideally suitable for determining the in-situ non-linear parameters for the design of laterally loaded piles. A method for designing laterally loaded piles using presuremeter data is presented. For driven displacement piles, which are commonly used offshore, the pressuremeter can be pushed into the soil in a similar full-displacement manner. Several case histories are presented to illustrate the proposed method.

Book Description
The nonlinear subgrade reaction method is widely used for the design of laterally loaded piles. This method replaces the soil reaction with a series of independent springs. The nonlinear behavior of the soil springs is represented by P-y curves, which relate soil reaction and pile deflection at points along the pile length. Most of the existing methods for obtaining P-y curves are highly empirical. Often little account is taken of the method of pile installation. The pressuremeter offers an almost ideal in-situ modelling tool for determining directly the P-y curves for a pile. As the pressuremeter can either be driven or self-bored into the soil, the results can be used to model either a displacement or a non-displacement pile.
