T R

he author did the experimental results and the Geotechnical analysis of sandy soil (Skikda city) himself, and the produced numerical model, which supports the conclusions in this work, is accessible upon request from the corresponding author.

PERSPECTIVES

einforcement is a well-known approach nowadays. The availability of fibre and cement has shown to be a solution in the laboratory for improving soil behaviour. Furthermore, the influence of additions on soil, ground characteristics (safety factor, displacements) may be numerically investigated.

A BBREVIATIONS

The following abbreviations are used in this paper: Cement content (CC). Fibre Length (FL). Oued Zour Sand (S1) with continuous line. Filfila Sand (S2) with discontinuous line. Polypropylene (PP). Consolidated drained (CD). Cell pressure (CP).

Mohr Coulomb Model (MC). The total displacement (Ut). The displacements in direction x, y (Ux), (Uy). 3% C+F12 means: 3% of cement, 1% of fibre length (12 mm). 3%C means 3% of cement. 0F means 0% fibre.
