Exemplary study of pile foundations Houssam Khelalfa

The present "GEOTECHNICAL Book" considers the following aspects: Geological and geotechnical characterization of foundation sites based on stratigraphic data (survey logs) and results of geotechnical surveys (in-situ and laboratory tests) carried out in different phases of study (Before Detailed Project -BDP and Study of Execution - ExS); Definition of the Reference Geological and Geotechnical Model for the project; Definition of the type of foundation and the piles selected for the sizing/ dimensioning calculation; Dimensioning of the elements of the foundation and verifications to the Ultimate Limit States (ULS); in particular, for piled foundations, the extreme loads/ stresses along the shaft (barrel) shall be determined; Calculations of the settlements in the Service Limits States (SLS); Estimation of the stiffness of the elastic springs at the base of the piles. Finally, we presented the Drawings and the Sequence of realization of the piles foundations.
