of 5 blocks or 1m. The first crack should correspond to the sliding surface of the
top backfill soil layer.
4.4 Chung Hsin Nai Lu Shi Park, Chung Hsin New Village
The park is located near Chung Hsin Stadium. Two reinforced soil structures
were constructed opposite to each other in this park. Both structures were
composed of three stacked walls (Fig. 10a) . Part of the structure facing west
collapsed, whereas the structure facing east was stable. The collapsed portion of
the wall was unreinforced and was supported at the back by the H-steel piles.
Note that some of the blocks were also damaged structurally (Fig. 10b). The
portion of the wall at the second level, which was reinforced, remained stable
(Fig. 10c). In this stable wall, the first reinforcement layer was placed 2 blocks
from the base, followed by 4-block, 3-block, and 5-block spacings, as marked by
the dry leaves in the picture.
This case history demonstrated the earthquake resistance of the reinforced
soil retaining wall compared to the unreinforced wall. The difference in
