Recently, mechanically stabilized earth(MSE) walls are gradually replacing
conventional concrete retaining walls for reasons of economy, expediency of
construction, and aesthetics. However, mistakes in design and construction of MSE
walls have resulted in many troubles such as failure of MSE walls, horizontal
deformational breakdown of facings, and so forth during or after construction.
In this study, the collapsed section of MSE walls with consideration for a field
study, design drawing and experimental data were reviewed. Also, the construction
process until the collapse of MSE walls was numerically modeled, and this study
tried to analyze the fundamental causes of the collapse.
As a result, firstly, the types of design drawing and structural bill were
confirmed to be different from each other. Secondly, the investigation revealed that
the bad-quality backfill were responsible for the collapse. Lastly, the process of
installing a soundproof walls at the top of the MSE walls confirmed that geogrids
in 0.3m and 0.9m depth were cut, and additional structure reviews were missed.
