Abstract
The geosynthetic reinforced retaining wall has been known as a highly cost-effective method for retaining wall. A new type bridge, geosynthetic-reinforced soil (GRS) integral bridge which combines integral bridge with geosynthetic reinforced backfill has been proposed. We performed a series of static loading tests and shaking table tests with small models to evaluate the stability of GRS integral bridge. The active failure and increment of earth pressure of backfill due to annual expansion and contraction of the deck is solved by geosynthetic-reinforcing of backfill. The seismic failure mechanism of GRS integral bridge is also revealed by shaking table tests. We performed another series of tests to consider the effect of structural condition to the stability of GRS integral bridge. The model test results and consideration of effect of structural condition on GRS integral bridge are summarised.
