Abstract

Seepage consolidation under normal gravity conditions can be used to prepare clay soil substrates for subsequent testing in a geotechnical centrifuge. Currently available information provides no information regarding the general efficiency of this method, which would be expected to vary widely depending on centrifuge, test specimen, and operating conditions. A numerical investigation is presented of the efficiency of the two-stage seepage/centrifuge consolidation method for the preparation of normally consolidated clay substrates. Large strain consolidation simulations and experimental data for centrifuge and seepage/centrifuge consolidation tests conducted on reconstituted Singapore marine clay are in excellent agreement. A parametric study illustrates the effects of initial specimen void ratio, initial specimen height, surcharge stress, swelling time, and acceleration factor on the efficiency of the two-stage substrate preparation method. Efficiency of the method for Singapore marine clay ranged from 55 to essentially 100 % for the simulations conducted.
