Abstract
This paper shows the results of numerical analyses of dynamic centrifuge model tests to investigate the seismic performance of the geotextile-reinforced soil wall with a double facing system. Such reinforced soil wall has a thin vertical gravel layer between the wraparound face and facing concrete panels to reduce the earth pressure acting on the facing concrete panels from reinforced backfill. To investigate the influences of presence of the facing concrete panels and lengths of geotextile on its seismic performance, a related paper has reported the dynamic centrifugal results of a geotextile-reinforced soil wall 20 m high under a 50 G centrifugal field; this paper reports the results of dynamic finite element analyses of the centrifugal tests, and compares the numerical and centrifugal results to clarify the seismic performance of the geotextile-reinforced soil wall with a double facing system.
