A FULL SCALE MODEL TEST OF GEOGRID REINFORCED SOIL WALL FOR ESTABLISHMENT OF IT’S MAINTENANCE METHOD

Abstract

For reinforced soil walls, the judgment of the healthy-unhealthy is usually carried out by the uniform control value, such as wall displacement. However, it is believed that many reinforced soil walls are stable with some deformation with age. The authors have proposed a maintenance method not monitoring a uniform control value but judging the presence or absence of functional deterioration factors. In this paper, we report the result of the various measurements by applying the proposed maintenance method in the 6m height geogrid reinforced soil wall model with cavity.
