EMBANKMENTS WITH LATERAL BERMS ON COMPRESSIBLE SOIL - DRAWING UP OF CHARTS FOR CALCULATING THEIR STABILITY

REMBLAIS SUR SOLS MOUS EQUIPES DE BANQUETTES LATERALES - ELABORATION DES ABAQUES DE CALCUL DE STABILITE

This report presents charts developed with a view to rapidly calculating the stability of embankments with side berms built on compressible soil. The main aspects of the calculation of stability (safety factor, etc.) are discussed. This study deals with: an embankment with berm consisting of entirely frictional materials, the sides of which have a gradient of 1/2; the homogeneous subgrade is characterized by constant undrained cohesion. The calculations were carried out on a computer by means of the bishop method. They take into account the shear strength in the embankment. The graphs give a direct value of the safety coefficient as a function of the geometric parameters of the embankment and of the subsoil, and the mechanical characteristics of the materials (embankment and subgrade). These charts are presented so that they facilitate the selection of optimum dimensions for the stability berm. /TRRL/
