ABSTRACT
Large earthquakes have caused damage to soil structures such as earth dams,
river dikes, and reclamation dikes. To prevent this, the reinforcement of soil
structures with geotextiles has been attempted. This chapter describes the
behavior of embankments reinforced with geotextiles (continuous fibers,
geogrids) in shaking table tests using embankment models. The shaking table
tests used small- and large-scale models constructed with sand. The test results
confirmed that reinforcement with geotextiles greatly decreases settlement
even if embankments and foundations were constructed with loose sand. Some
results of the shaking table tests of models reinforced with continuous fibers
