A Critical Review of Full-Scale Shaking Table Tests Conducted on Reinforced Soil Retaining Walls - Reinforced Soil Engineering: Advances in Research and Practice - page 490

was used. The reinforcement layers were 40% of the wall height, but similar to
field construction, a few layers were tied to the opposite side of the wall.
The wall was subject to three phases of shaking: A, B, and C. In A, the
acceleration (3.4 Hz, 20 sec duration) was applied in nine stages, in nine stages,
from 100 gal to 500 gal with an increment of 50 gal. In B, a real Japanese
earthquake record was used, whereas in C, the accelerations of 200 gal and 400
gal were applied after saturating the foundation.
The test results indicated almost no amplification of acceleration up to mid-
height of the wall (Fig. 14). The horizontal displacement of this wall was very
small during shaking, less than k1 cm (Fig. 15) , because it was developed to
Figure 14 Amplification ratio in JR wall. (From Murata et al., 1994.)
