STATIC STABILITY OF GEOTEXTILE-REINFORCED SOIL WALL WITH DOUBLE FACING SYSTEM

Abstract

The geotextile-reinforced soil wall with double facing system has a vertical layer to absorb the deformation between the facing concrete panels and reinforced backfill. Authors carried out field observation for several walls and confirmed static stability of the walls. Additionally, in order to evaluate static stability of the wall, numerical analysis is carried out. This paper reports that results of field observation and numerical analysis of the wall, which the maximum height of 14.2m and the back-slope is continued to a height of 25m, and the wall is stability state after construction.
