摘要
The main reason for earthquake-induced landslides is liquefaction of soil,a process considered to occurmostly in sandy soils.Liquefaction which occurs in clayey soils has also been reported and proven in the recent litera-ture,but liquefaction in clayey soils still remains unclear and there are many questions that need to be addressed.Inorder to address these questions,an depth study on the liquefaction potential of clayey soils was conducted on the ba-sis of field investigation and a series of laboratory tests on the samples collected from the sliding surface of the land-slides.The liquefaction potential of the soils was studied by means of undrained cyclic ring-shear tests.Research re-sults show that the liquefaction potential of sandy soils is higher than that of clayey soils given the same void ratio；the soil resistance to liquefaction rises with an increase in plasticity for clayey soils；relation between plasticity indexand the liquefaction potential of soil can be used in practical application to estimate the liquefaction potential of soil.
