Abstract
Countermeasure techniques against earthquake-induced liquefaction aim to mitigate damage on infrastructures. Vertical drains performance has been evaluated during the last decades showing effectiveness in the reduction of structural damage. The performance of alternative drain arrangements considering the influence of existing buildings have been recently analyzed showing positive results on foundations settlement reduction. Although geotechnical mitigation measures main objective is to reduce detrimental effects in buildings, it is also important to incorporate economic and environmentally sustainable solutions. In this paper, the use of recycled coarse material inside drains such as high permeable rubble brick obtained from post-earthquake debris or buildings demolition is examined. Dynamic centrifuge test series was carried out to evaluate the performance of rubble brick vertical drains placed around existing foundations with different loads. The study shows the influence of the foundation load variation on the excess pore pressure generation due to earthquakes, the following post-seismic dissipation, and the foundation response.
