Displacement measurements of ground and piles in sand subjected to reverse faulting

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).…”

“…Many studies apply seismic loading either utilising input motion recorded during real earthquakes (e.g. Pérez-Herreros et al 2018) or idealised sinusoidal motion, however Yao et al (2018) have created an experimental apparatus to directly model the movement of a fault and used this to investigate the effect this has on piles close to and within the fault zone. This work also uses laser displacement transducers to measure the movement of the pile head and presents a good comparison between these measurements and those obtained from DIC.…”

“…Qi & Knappett (2018) and Ghalandarzadeh & Ashtiani (2018) both present work relating to the response of shallow foundations under seismic loading. In the paper of Ghalandarzadeh & Ashtiani (2018) a similar approach to that taken by Yao et al (2018) is adopted whereby an apparatus is developed that induces a predefined fault plane into the soil model and the response of the foundation to this is monitored. The footing load was generally maintained constant with embedment and distance from the fault plane being varied.…”

“…The magnitude of the footing load appears to have little ef-fect upon this result. As with Yao et al (2018) the zone of influence of the fault is quite large so foundations are affected wherever they are placed within the experiment. Qi & Knappett (2018) investigate the influence of soil permeability on shallow foundations (supporting a low-rise structure).…”
