Abstract: In order to simulate the fines content effect on the liquefaction properties of tailings, the tailings were sieved and then were mixed according to different fines contents to prepare samples. Based on a lot of dynamic tests of these tailings samples, the effect of fines (d < 0.074 mm) content on the dynamic liquefaction of tailings was analyzed in detail. The study result has shown that when the fines content is about 35 %, the liquefaction resistance of tailings is the best. Based on the dynamic experiments and lots of standard penetration tests in situ, a modified formula is presented to take the effect of fines content on liquefaction properties into account. The modified formula can analyze the effect of fines content on the liquefaction resistance of tailings material. Consequently, the modified formula can evaluate liquefaction strength of tailings material more accurately.

Key words: fines content, soil dynamic experiments, tailings material, liquefaction properties, standard penetration test, liquefaction resistance
