from the blast cut the PET yarns and the PP base of the geotextile. Spiral-shaped
holes were formed behind the geotextile facing at all those areas where the
geotextile were torn. Small pieces of blast fragments were found embedded in the
holes. Hence it was concluded that the reinforced soil was effective in absorbing
the blast fragments. Some soil mass fell out to the front of the RS wall from the
areas where the geotextile facing was torn.
Figure 7 shows the condition of the RS wall after detonation event MD5-
E3. The areas of melted geotextile facing increased and the extent of melting
deteriorated further. The areas of geotextile cut by blast fragments also increased,
and the degree of damage was more severe than the conditions after the previous
detonation event. More soil mass and some of the sandbags placed at the top of
the RS wall fell out to the front of the RS wall. Despite the above deterioration,
the RS wall stood up vertically except that some soil mass fell out from the torn
facing area. In addition, there was slightly more compression on the facing.
