Various types of reinforced retaining walls have been recently developed and adopted. On these retaining walls, however, effects of frost heaving damage prevention measures have not yet been clarified. In this study, a full scale model of a multi-anchored retaining wall was installed in the field, and measurements were performed over four winter seasons. Following results were obtained; 1) measured freezing fronts were associated with measured freezing earth pressure on facing blocks; 2) earth pressure on facing block repeated seasonally between 40-50kpa in winter and 5-10kpa in melt season; and 3) the effectiveness of thermal insulation material and frost-nonsusceptible backfill against frost damage was evidently recognized.
