Abstract
Two definitions of fines, soil particles finer than the No. 200 sieve (0.075 mm) and No. 400
sieve (0.038 mm), are adopted to evaluate the effect of fines content on the liquefaction resistance
of the silty soil in the Maoluo River area of Nantou City. The specimens of different fines contents
according to these two definitions of fines were prepared by moist tamping to a dry density of 1400
kg/m3. The liquefaction resistance of these specimens were tested using the cyclic triaxial test
apparatus and the cyclic torsional shear device. Comparisons were made between the liquefaction
resistances of soils containing fines according to different definitions. The results show that the
effect of fines on the liquefaction resistance of Maoluo River soil is more pronounced and
consistent based on the fines content defined as the portion finer than the No. 400 sieve than that
with fines defined as soil passing the No. 200 sieve.
