Exemple de stratification horizontale artificielle de sols initialement homogènes par densification ou rigidification (structure 1D). Le profil des vitesses des ondes de cisaillement est modifié (à droite) après travaux de densification par compactage dynamique, vibrocompactage ou injection de coulis (ligne rouge pleine).

Example of artificial horizontal stratification of initially homogeneous soil by means of densification or reinforcement (1D structure). The shear wave velocity profile is modified (right) after dynamic compaction, vibrocompaction works or grout injection (solid red line).
