GEOSYNTHETIC REINFORCEMENT FOR EMBANKMENTS OVER DEGRADING DISCONTINUOUS PERMAFROST SUBJECTED TO PRESSTRESSING
ABSTRACT: Failures of road embankments on discontinuous permafrost commonly occur during thawing of the foundation soil. As an approximation, weak zones created by thawing of discontinuous permafrost can be considered as ‘voids ’ within the foundation. Geosynthetic reinforcements have been used to b...
