Seismic Performance Modeling of Geosynthetic Reinforced Slopes

Lee, W. F. / Chen, J. W. / Lin, S. S. / Huang, Y. M.

Geosynthetic reinforced soil (GRS) walls have become an important applications of retaining structures in earthquake Asia areas such as Taiwan and Japan. In this paper, the authors first present a numerical model that is capable of simulating dynamic response of GRS slopes. Shaking table results were studied in developing the model. An updated model, "rigid cable box" model, is then developed to simulate GRS wall. Also a selected GRS wall case, that failed during the 921-Chi-Chi earthquake, is then studied with the developed model and real earthquake records in an effort to observe seismic performance of GRS walls. Conclusions and discussion of this paper are hoped to be helpful to the seismic design of GRS walls.
