Comparisons between theoretical and observed behaviour of pile foundations

The paper describes a number of case studies in which the deformation behaviour of single piles or pile groups has been calculated theoretically and compared with the observed behaviour. The cases include: (a) the settlement of two grout injected test piles in sand, for which "class a" (before the event) predictions were made, (b) the settlement of steel pipe piles and step taper piles in a soil profile consisting of clay overlying dense sand, (c) the lateral response of two test piles, the predictions being based on pressuremeter data, (d) the lateral load deflection behaviour of pile groups tested in rumania, (e) the settlement of a large office block founded on rock socketted piles. In the last two cases, the results of tests on single piles have been used to predict group behaviour. The theoretical approach used for the calculations is based on elastic theory and is outlined briefly in the paper. The selection of the required soil parameters is also discussed. It is concluded that the theory used can give quite acceptable estimates of pile performance, particularly if used in conjunction with test pile data (a).
