Abstract
The application of reinforced soil concept in earth retaining structure is getting popular nowadays. The Geogrid Reinforced Retaining Wall is often compared to RC Cantilever Retaining Wall due to its better advantages in many aspects. This final year project is concerned with the comparison between Geogrid Reinforced Retaining Wall and RC Cantilever Retaining Wall from engineering aspect based on a company project. Well known geotechnical finite element analysis software, PLAXIS V8 is used as analysis tool in this study. The retaining wall’s behavior in post construction was investigated. It was found that the Geogrid Reinforced Retaining Wall deform lesser than RC Cantilever Retaining Wall. The trend of stress distribution in the soil is different from each other. The factor of safety of Geogrid Reinforced Retaining Wall is also higher. Besides that, the performance of retaining wall with different ground condition and backfill material is studied as well. The results are more evident in which the Geogrid Reinforced Retaining Wall has smaller displacement in wall facing as well as soil body. The differential settlement in Geogrid Reinforced Retaining Wall is small compared to RC Cantilever Retaining Wall in which can be observed in displacement contour map diagram.
