Description
This study investigates the performance of geotechnical filter on mitigation of internal erosion of earth structure in costal facilities. Gravels with various particle size distribution were examined as the candidate material for geotechnical filter. In addition to the filtering (clogging) effect with the reclaimed sand, the stability of the geotechnical filter against the riprap was evaluated by a series of shaking table test. Furthermore, the modelling test revealed that the geotechnical filter mitigates the damage of geotextile due to both aircraft load and seismic motions.
