Abstract: 

Cyclic Loading produced by earthquake can induce liquefaction in saturated loose sands containing fines. In this investigation, the effect of plastic fines on the liquefaction strength was studied by considering both sand and fines. The tests were performed by implementing a cyclic triaxial apparatus.
Tests results reveal that increasing the fines content to 20 percent (PI=4) decreases the liquefaction strength. By increasing the fines content to more than 20 percent the liquefaction strength increases so that for the specimens containing 40 percent (PI=7), the liquefaction strength is about the value clean sand. The results indicate that the presence of fines content does not increase the liquefaction strength and conversely decreases it significantly. Thus, using conventional methods of evaluating liquefaction potential such as SPT are not conservative if sand contains plastic fines.
