The effects of the plastic index on the shear moduli of clayey soils were investigated in a resonant column device and a dynamic triaxial test apparatus. It was found that the plastic index affects the low amplitude shear modulus, stress-strain curve and secondary increase in shear modulus. The laboratory. test results were compared with the results obtained from in-situ seismic. survey. The differences of both test results were observed and were discussed. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
