It is important to determine the capability of any reinforced soil wall. The expected magnitudes of stresses, failure modes, bearing capacity and displacements should be determined and checked if they are within the allowable serviceability limits provided by design standards. In this paper, both analytical and numerical analysis and design of reinforced soil walls was carried out with the objective of establishing the various parameters which are key to performance of reinforced soil walls. Stresses, displacements, bearing capacity, settlement and failure modes were determined as key parameters in this research. In addition, advantages of reinforced soil walls were also established. Analytical equations for analysis of reinforced soil walls were used based on empirical data. Similarly, finite element analysis was carried out using Plaxis 3D program. Soil model element measuring 6m (wide) by 8m (high) was used for analysis in both cases. The soil model was subjected to a uniformly distributed loading of 15kPa acting as surcharge on soil. The results of analytical calculations of the soil model representing a reinforced soil wall showed that it was sufficient in terms of stability. These were checked by determining the factors of safety against sliding and overturning which were found to be 2.077 and 4.26 respectively. These were higher than 2.0 which is the minimum factor of safety for walls hence were safe. Maximum geogrid spacing was found to be 2.5m while minimum geogrid spacing was found to be 0.7m. A graph was plotted to show the relationship between depth and geogrid spacing. The results from FEA were relatively different from the analytical results since the software displays the results in terms of maximum, effective and extreme deformations. Nevertheless, the results from the FEA also showed that the reinforced soil model was safe under the conditions to which it was exposed. From the results of the analysis, analytical and numerical methods had differences. These were attributed to factors like time, nonhomogenity of soil being analysed and collapse of soil model during analysis using plaxis software. The recommendations from the results of the research suggested that plaxis software should be made better by including more complex analysis tools which takes into account time and non-uniformity of the soil during modelling. Laboratory and field data\a should also be included within the software to enable comprehensive analysis which is more practical.
