MODEL EXPERIMENT FOR DYNAMIC BEHAVIOR AND SOIL NAILING OF EMBANKMENT AFFECTED BY FREEZE‐THAW

Abstract

There are few reports on the effect of ground freezing on the dynamic characteristics of the embankments that deal with experimental research efforts covering the deformation and decomposition of the embankments and their countermeasure constructions. In order to determine the earthquake behavior of the embankments in cold regions and an improvement in earthquake resistance provided by the soil nailing, this study has conducted a vibrating table experiment on an embankment model. Results from the experiment show that the earthquake resistance slightly deteriorated when the natural ground reinforcing materials sustained damage from freezing-thawing.
