Investigation on the aseismic performance of pile foundations in volcanic ash ground

Physical modelling applied to infrastructure development

“…A number of papers investigate the performance of piles under seismic loading. The experiments consider single piles (Yao et al 2018, Ebeido et al 2018, Chen et al 2018, Pérez-Herreros et al 2018 or small pile groups (Imamura 2018, Egawa et al 2018. One paper (Garala & Madabhushi 2018) considered a comparison between a single pile and a small pile group (containing three piles).…”

“…The authors conclude that, as in the real case, piles within the fault zone would most likely be completely sheared. Egawa et al (2018) present a series of tests on piles within layered soil models. The soils used are sand and volcanic ash and a variety of arrangements were tested (with respect to number and thickness of each layer).…”
