TL;DR: Pile-supported marine structures are generally subjected to lateral loads caused by earthquakes, waves, currents, etc. p-y curves are traditionally used to evaluate the response of a pile under lateral loads as mentioned in this paper.

TL;DR: In this paper, the effect of including the stiffness of the superstructure in the analysis of the foundation is examined, and it is shown that the type of structure and its stiffness can have an effect on the deformation of a foundation.
Abstract: Interaction of a structure and its foundation with the soil is discussed in this paper, and some of the numerical and analytical methods that have been developed for the analysis of raft and piled raft foundations are presented. It is shown that the use of simple spring models for the soil behaviour can lead to erroneous result and it is recommended that their use should be discontinued. Simple finite layer techniques are also examined, and results are compared with those of three-dimensional finite element techniques. It is shown that the finite layer techniques can yield good results for displacements in the raft and for moments induced into the piles. It is also shown that the use of thin plate theory for the raft can give good results for thick rafts and can be used for raft and piled raft analysis. The effect of including the stiffness of the superstructure in the analysis of the foundation is examined, and it is shown that the type of structure and its stiffness can have an effect on the deformation of the foundation. Finally, an analysis of an instrumented structure is carried out, and it is shown that reasonably good predictions of the behaviour of the foundation can be made through the use of soil-structure interaction theory and finite layer techniques.

TL;DR: In this paper, the authors studied the three-dimensional axisymmetric Boussinesq problem of an isotropic half-space subjected to a concentrated normal quasi-static load within the framework of dipolar gradient elasticity involving linear constitutive relations and small strains.
Abstract: The three-dimensional axisymmetric Boussinesq problem of an isotropic half-space subjected to a concentrated normal quasi-static load is studied within the framework of dipolar gradient elasticity involving linear constitutive relations and small strains. Our main concern is to determine possible deviations from the predictions of classical linear elastostatics when a more refined theory is employed to attack the problem. Of special importance is the behavior of the new solution near to the point of application of the load where pathological singularities exist in the classical solution. The use of the theory of gradient elasticity is intended here to model the response of materials with microstructure in a manner that the classical theory cannot afford. A linear version of this theory (as regards both kinematics and constitutive response) results by considering a linear isotropic expression for the strain-energy density that depends on strain gradient terms, in addition to the standard strain terms appearing in classical elasticity and by considering small strains. Through this formulation, a microstructural material constant is introduced, in addition to the standard Lame constants. The solution method is based on integral transforms and is exact. The present results show significant departure from the predictions of classical elasticity. Indeed, continuous and bounded displacements are predicted at the points of application of the concentrated load. Such a behavior of the displacement field is, of course, more natural than the singular behavior exhibited in the classical solution.

...4], and Selvadurai [5]. The Boussinesq solution is of fundamental importance in geotechnical applications including soil-structure interaction and stability, earthquake prediction, and rock mechanics [6,7]. In fact, the solution serves as the pertinent 3D Green’s function utilized to determine the stresses and displacements induced by general load distributions, thus, rendering it a very useful tool in...
