Determination of the Typical Profile of the Land and of the Solicitations Acting on the Piles

A good knowledge of the global characteristics of the soil is essential in the execution of any civil engineering work. It constitutes, indeed, one of the main elements of the choice of the solution for the crossing. In this respect, it should be emphasized that in the case of current structures, the cost of geotechnical reconnaissance represents a significant percentage of the total cost of the project. The objective of this work is based on the determination of the standard profile of the land to accommodate the structure plans to build and characteristics of different layers of soil for sizing foundations. In this work, we used investigations (Insitu tests) such as: soundings to determine the general characteristics of soil layers such as: position, thickness and homogeneity; likely to be interested in the foundations. The study led to the determination of: - The average limit pressure - The average pressure module - The typical profile of the land - The critical embedding depth of the foundations - The stresses in the piles
