Analyse comparative de la norme NF P 94 282 sur les écrans de soutènement

Abstract : The first part of this work is dedicated to the description and the definition of the application field of the more usual flexible retaining walls (sheet pile walls, diaphragm walls, soldier beams and lagging) and of different support systems. The second part of this work presents the main development stages of the four current design methods for flexible retaining walls, namely:
• classic methods
• the subgrade reaction method
• the finite elements method
• empirical and semi-empirical methods
This second part ends presenting the normative context currently in force and more particularly the standard NF P 94 282. In accordance with the Eurocodes, this standard integrated a semiprobabilistic approach and the use of partial coefficients for the flexible retaining walls design, letting the designer choose the hypothesis and the design method. In view of the above, the third part of the work presents, using comparative calculations, the impact the hypothesis and/or the choice of the design method can have on the flexible retaining wall design. The purpose of this is to permit to prime contractors, contractors and geotechnical engineering consultants to have a broader vision of the standard NF P 94 282 possibilities and to permit them to optimize the structures which they are responsible for.
