BEHAVIOR & STABILITY ANALYSIS OF GEOGRID REINFORCED EARTHWALL: A CASE STUDY IN VIZIANAGARAM (A.P)

Reinforced Earth (RE) wall offers a variety of advantages when compared to conventional retaining walls and embankments for road approaches. This study is carried out on proposed RE wall design for an approach road on Visakha side using finite element based computer program “PLAXIS 2D (version 8.6)”. The proposed Design which is to be executed in the near future is based on limit-equilibrium approach. The main aim of this study is to find out the Deformation of this RE wall along with its Stability using finite element approach. The Global factor of safety of this Geotechnical structure is also determined using PLAXIS 2D. PLAXIS 2D is a finite element analytical geotechnical Software which gives accurate results compared to that finite difference and limit equilibrium analytical software's. Detailed study of the Design (using limit-equilibrium approach) acquired from the ongoing project site is
