Cohesive-frictional backfill used in reinforced earth-wall for Seismic analysis

Abstract

A reliable technique based on limit equilibrium for a failure wedge of a reinforced vertical wall with cohesive-frictional backfill which undergoes a seismic acceleration pertains to the pseudo-static assessment has been reported in this work. The procedure is aimed to assess the inextensible reinforcement which is undergoing oblique pullout by considering the effect of modest cohesion and surcharge. The oblique pull under seismic stress usually has ramifications for various parameters such as reinforcing strength (k), sliding wedge size (L/H), and safety factor (F_ST). It is observed that the stability of the Reinforced earth (RE) wall has improved by increasing the angle of internal friction of the soil. The factor of safety is greater in the static situation than in the dynamic case and there is less difference in cohesiveness as kh increases. Inextensible sheet reinforcement of the normalized displacement is proportional to the transverse force, because the angle of shear and the cohesion (c) increases with in Factor of safety (F_ST) due to the shear/bond resistance.
