Abstract
Currently, the reinforced earthwork method using band steel reinforcement which is most widely adopted in Japan has many practical achievements even in snowy cold areas such as Hokkaido. However, several cases of deformation due to the frozen embankment have been reported. On the other hand, the detailed mechanism of the deformation of the steel reinforced earth wall has not been clarified. In this study, we constructed Terre-Arrme reinforced soil walls with two embankment materials, frozen and nonfrozen. As a result, a large tensile force and a local strain occurred when the soil behind the wall panel was frozen under the condition that tension force was applied to the reinforcing material installed in the embankment with high frostability material.
