Abstract
Geosynthetic reinforced slopes perform reasonably well under earthquake loading conditions as we already know. Consequently, the seismic response of the geosynthetic reinforced slope is worthy to be explored in detail. This study sets earthquake monitoring system for the geosynthetic reinforced slope built in FoGuang University, Ilan, Taiwan. There are totally 3 seismic instruments arranged to record the acceleration time histories of the ground surface, the middle portion and the top portion of the geosynthetic reinforced slope. The recorded acceleration data can be used to understand the seismic response of geosynthetic reinforced slope straightforwardly. The amplification factor for the geosynthetic reinforced slope is discussed in this paper using the recorded data. In addition, this study also simulates the seismic response of geosynthetic reinforced slope, using the acceleration time history recorded at the ground surface from the site, utilizing the finite element computer program PLAXIS. Finally, the predicted results obtained from PLAXIS finite element program are compared with the records from the seismic monitoring system. The agreeable comparison results give us the confidence to explore the seismic response of geosynthetic reinforced slopes by means of numerical technique.
