Abstract:

The use of non-biodegradable and reinforcing materials in soil mass enhances safety with a highly cost-effective and dependable method. In this study, we used the limit equilibrium analytical technique to numerically determine the total internal and external stability performance of retaining walls using seven different height models. The reinforcement allows the soil mass to withstand strain in ways that the earth could not alone. Because stresses formed within the mass are transmitted from the soil to the reinforcing strips through friction, the internal friction of the soil is the source of this tension resistance. The parametric and comparative investigations yielded a wealth of information concerning the internal and exterior stability of reinforced earth-retaining walls. In this study, galvanized steel strips and geotextiles are engaged as reinforced elements in the reinforced soil. We demonstrated the energy difference between these two sorts of components. In this paper, we look at serviceability through internal stability to enhance the wall's service life and factor of safety against overturning, sliding and bearing capacity failure. The major goal of this study is to compare the factor of safety against failure (pullout, strip breaking, bearing capacity, overturning, sliding, and so on) between reinforced and unreinforced models generated using numerical analysis to see which is more constructive. After numerical analysis, we found that the value of the factor of safety increased significantly in all types of failures. Not only that, but we also find out which is more reliable between strips and fabrics.
