Shaking Table Tests of Embankment Models Reinforced with Geotextiles - Reinforced Soil Engineering: Advances in Research and Practice - page 400

Figure 29 Observed displacement and acceleration at crest: (a) nonreinforced; (b)
reinforced with geogrid.
From the above information, it was confirmed that in both the large- and
small-scale models, geogrid reinforcement helped reduce crest settlement of
embankments.

4.2.1 Test Procedures
The model dam used in this test was a 6-m-high uniform-type earth dam that
failed during the Hyogoken-Nambu earthquake. Figure 30 shows the state of
