Besides of the requirement of good quality and relevant soil data, important knowl edge can be gained from field experiments, particularly with the use of instrumented xvi piles, as presented in Chapter 8, or from recording the performance of completed struc tures. Modern methods of monitoring make entirely feasible the acquisition, under service conditions, of such information as pile-head deflection and other such data.

To reconstruct the sand samples, the new designed apparatus, Mobile Pluviator, was adopted. An increasing of the number of piles in-group decreases the group efficiency owing to the increasing of overlapped stress zones and active wedges.

It may be more in the loose sand. Introduction Superstructures are supported by pile foundations so that it had its origin in prehistoric time.

These foundations may be subjected to significant horizontal loads such as dynamic and static loadings. Two criteria shall be controlled to satisfy of functioning such structures: 1 their deflection which must be within the permissible limit and 2 safety of pile against ultimate failure. The behavior of the pile group and the single pile is usually different owing to the impacts of the pile-to-pile interaction so called shadowing effects.

In addition, soil-pile coupling behavior is important when the load transfer occurs [ 1 ]. Evaluation of the pile group behavior and the soil-pile interaction has developed by several investigators in experimental and analytical modeling [ 2 — 4 ].

Existing methods of the analytical modeling can be classified into numerical approaches, Beam on Nonlinear Winkler Foundation method BNWF , and simplified formulations [ 5 ]. Although most of these approaches are attended on evaluation of the stiffness of the soil-pile system, they are less focused on the bending moment and the lateral resistance of the group.

It is worth noting that the estimations of ultimate lateral resistance and lateral subgrade modulus within a pile group are known as they are the key parameters in the soil-pile interaction phenomenon.

Several theoretical methods have been developed to determine these parameters in cohesionless soils.

However, the predictions of these approaches are often different. On the other hand, the laterally loaded pile group behavior has received a little attention.

Moreover, the experimental data on the determination of active pile length and bending moment are inadequate. Solutions of the relevant differential equations in finite difference form became pos sible with the emergence of the main-frame digital computer for routine computations in the 's.

Solutions on the personal computer can be obtained today with relative ease, allowing the sensitivity analysis of many significant parameters.

Under Lateral Loading

Improvements of computer codes are occurring at a rapid pace, and experimental data on the response of single piles and pile groups to lateral loading is appearing in the technical literature with regularity. The p-y method can be used to attack a wide variety of problems encountered in practice, as demonstrated by the examples given in Chapter 6. While the computer codes can be used to attack such problems and vast quantities of tabulated results and graphical results can be produced with ease, the importance of competent engineering judgement cannot be over emphasized.

For example, the computer codes will lead to the required penetration of the pile supporting an overhead sign subjected to wind loading; however, the knowledgeable engineer will have to note that in many cases too few data are available to validate such a result and will take appropriate steps to ensure a safe design. One such step could be the performance of a controlled set of experiments.

Besides of the requirement of good quality and relevant soil data, important knowl edge can be gained from field experiments, particularly with the use of instrumented xvi piles, as presented in Chapter 8, or from recording the performance of completed struc tures.

The pile can then be employed at the starting point for the p-y method of analysis. Van Impe and Mr.

Not much experimental data is available on which to base a method of computation. The value of f'c is the characteristic value of the compressive strength of the concrete. The problem of pile-soil-pile interaction for axial loading is discussed and recommendations are made for formulating influence coefficients to account for close spacing.
