Liquefaction of Dilating Sand
The occurrence of liquefaction in the form of decreasing shear resistance in saturated sands has been investigated under small departures from the undrained condition. Volumetric deformations are inevitable in field problems on account of the spatial variation in excess pore pressures generated during the earthquake shaking and their subsequent dissipation. An experimental investigation is presented to show that small expansive volumetric strains, if they occur either during or after the loading event, could transform a sand that is dilative under truly undrained loading into a strain softening, liquefiable type. This amounts to erring on the unsafe side. Practical implications of the findings are discussed.
