LARGE-SCALE SHAKING TABLE TESTS ON MODULAR-BLOCK REINFORCED SOIL RETAINING WALLS

The paper presents an experimental study of an earthquake performance of modular-block reinforced soil retaining walls which were backfilled with sand using large scale benchmark shaking table tests. The reinforcements used were polymeric geogrids, which were frictionally connected to the facing blocks having a front lip. In addition to observing the seismic performance, the purpose of testing was to generate quality data for future validation of numerical procedures. Three large scale 2.8 m high modular-block geosynthetic-reinforced soil walls were subjected to significant shaking using the Kobe earthquake motions. The test results indicated that the walls deformed very little with negligible horizontal acceleration amplification when subjected to the first shaking load. Amplification ratio of 1.35 indicated that the particular wall system performed better than conventional walls that had been tested for earthquake loading.
