After ward, a historical review of the reinforced soils. The different mechanical behaviors of the soil are presented , and at the end of this chapter there is the fib er reinforcement which is an innovative solution for soil improvement. In the second chapter, the met hods of analysis and regulation s are exposed. This chapter illustrates the sizing methods according to European and American standards. Although it ends with the study of seismic stability of this type of reinforcement. Chapter 3 develops an analytical stu dy of a real case of a reinforced wall in Tripoli. Following the presentation of the results of the reference case . A parametric study is performed according to the parameters that govern the behavior of this type. Knowing that this type of work is composi te, the phenomena of instability can be coupled. In chapter 4, the problem is approached using numerical model l ing by finite elements. The results of a parametric analysis are also presented. In order to show the importance of the use of fibers for soil i mprovement, a study of the behavior of this type of work is carried out using fiber - reinforced soils. The results are presented in Chapter 6. Chapter 6 summarizes the main results of a comparative study of the different analytical and numerical modelling a nd comparing the performance of geogrid e - reinforced soils with and without fibers , which makes it possible to identify recommendations for g eotechnical engineers who confronted the sizing of this type of works .
