Improvement of structural stability of embankment on slope against rainfall by using geosynthetic-reinforced soil wall with drainpipe

Abstract

A series of laboratory model tests were performed to investigate the methodology of improvement of the structural stability of embankment on slope against rainfall. In this study, the effects of geosynthetic-reinforced soil as well as drainage and filtration technologies on the stability of soil structure against rainfall were focused. As the results of experimental investigation, it was confirmed that the stability of soil structure against rainfall can be improved effectively by applying the geosynthetic-reinforced retaining wall to the toe of the embankment with drainpipes which can be maintained in working period to keep the function.
