Abstract
Cyclic undrained behavior were investigated by means of triaxial and torsional shear tests on undisturbed and reconstituted samples of two kinds of sands including fines. Based on the test results, a simplified method is proposed for the estimation of liquefaction potential of sand deposit by critical number of loading cycles, (Nc)cr. The estimated liquefaction strength curves for six kinds of sand deposit were almost coincident with test results until the double amplitude axial strain becomes around 2%, verifying a considerable potential of the proposed method.
