Presenting our research work at 7th International Conference on Earthquake Geotechnical Engineering entitled: ” Evaluating liquefaction resistance of recycled geomaterials using energy-based method and stress-based method “

Abstract:

series of consolidated undrained cyclic (CU) triaxial tests were performed to study liquefaction resistance of gravel and Gravel Tire Chips Mixture (GTCM). Samples were prepared at different volumetric fraction of gravel in the mixture and cyclic triaxial tests were conducted under different confining pressure. The energy-based method using the cumulative dissipated energy concept was employed in the liquefaction assessment of GTCM. These were compared to the conventional stress-based method. Results showed that liquefaction resistance are highly influenced by gravel fraction in GTCM. Furthermore, liquefaction resistance was found to increase with decreasing the confining pressure.
