“…These problems relate to bearing capacity failures, intolerable total and differential settlements, large lateral pressures, and slope instabilities. Several studies showed that the principal cause of several landslides, which affected the East-West highway in Algeria, is the presence of clayey formations [6][7]. A variety of ground improvement techniques have been used to address the concerns on soft soil foundations, such as geosynthetic [8][9][10][11], geogrid [12][13][14], pile [15][16], PVD [17], soil nail [18][19], chemical injection and grouting [20], stone column [21][22][23][24], and rigid inclusions [25][26][27].…”

Soft soils are widespread in many areas of the East-West highway of Algeria, covering large areas. Construction projects such as highway embankments, airfields, roads, and railways in such areas experience several problems due to their low strength and permeability. This study used a fully dynamic analysis to evaluate the dynamic response of a highway embankment. The numerical analysis was carried out using the FLAC 2D version 8.10 software. The main objective was to evaluate the effect of rigid inclusions on the dynamic response of highway embankments by monitoring settlement, shear-strain curves, and maximum soil accelerations and displacements at different depth points. The obtained results showed that the configuration of the rigid inclusions significantly influences the dynamic response of the model. For instance, the settlement at 0.9m is 16% higher than at 0.2m from rigid inclusion.
