Robustness of the P-RAT in the Shear-Wave Velocity Measurement of Soft Clays

Investigation of small- to large-strain moduli correlations of rockfill materials — application to Romaine-2 dam

“…, as they can transform electric pulses into vibration waves and vice versa. Recent experimental studies(Gamal El-Dean 2007; Ethier 2009;Éthier et al 2011;Karray et al 2015;Elbeggo et al 2019;Hussien and Karray 2021) have been conducted using an innovative P-RAT developed at the Université de Sherbrooke to advance the interpretation method of output signals during V s measurements. The ability of this technique to be easily incorporated into traditional geotechnical apparatuses, such as triaxial and oedometer cells, makes it a powerful tool for several applications.Conventional oedometer test procedures were applied during the preparation and consolidation of medium-size rockfill specimens with 280 mm diameter (d) and 90 mm height (h) (Fig.3-a).…”
