“…[8,24]; thus the contribution of Louis Ménard (the miracle inventor) has mainly consisted in defining the pressuremeter characteristics of soils (limit pressure intervenes in the calculations of stability of the foundations (the bearing strength of the superficial foundations) and the pressuremeter module is used for the calculations of settlement) [4,9,13,16,20]. According to fascicle 62, the estimate of the breaking stress from the limit pressure [10,22,23], is in the following form:…”

This work has two axes: The first one is theoretical (bibliographic analysis) on the theoretical estimation of the settlement under a Shallow foundation with the contribution of the characteristics of the results of the pressurometric tests and the second numerical axis by the numerical evaluation of the settlement generated by a superficial foundation that always happens by estimating the carrying capacity of these foundations by two methods the first is the classical method and the second the empirical method based on the direct interpretation of the in situ test such as the pressuremeter test by the determination Pressuremeter characteristics (Limit pressure (Pl) and the Pressuremeter module (EM)), our contribution consists in using a calculation code based on the finite element method with the contribution of two laws of elastoplastic behavior namely Mohr-Coulomb and Cam- Clay we use geotechnical survey results project of the railway line project (Tissemesilt-Alger-Bughazoul) in Algeria.

“…6(b)). When subjected to significant magnitudes of thermal loads, fine-grained soils can show a temperature sensitivity of their elastic properties (Eslami et al, 2017). However, this sensitivity is limited in magnitude if not absent in many situations.…”

Over the past twenty years, an increasing amount of research has been performed to understand the multiphysical behavior and to address the geotechnical and structural design of so-called energy piles, i.e., deep foundations that can serve any superstructure as both structural supports and geothermal heat exchangers. The coupled application of thermal and mechanical loads to energy piles, due to their multifunctional operation, represents a challenge. Currently, knowledge about the response of energy piles subjected to thermal and mechanical loads is accessible, along with some design guidance. However, this knowledge is fragmented and no recognized performance-based design framework is available. Looking at such challenge, this paper presents a theoretical and experimental analysis of the multiphysical behavior of energy piles, as well as a performance-based design framework for such foundations. The work highlights that thermal loads involve effects that can be neglected in the design of energy piles at ultimate limit states and can be considered relevant only at serviceability limit states. Based on this result, the performance-based design of energy piles at ultimate limit states reduces to a conventional pile design process while the design at serviceability limit states must account for a number of proposed verifications.
