The effects of consolidation stress history including consolidation stress ratio, OCR and cyclic loading with drainage on the undrained shear strength of cohesive soil were investig toted. The ratio$(S_u/sigma'_{vc})ckou/(S_U/sigma_{vc})cuv$ was observed to increase with increasing OCR. The equation (1) in this paper by Mayne(1980) for the undrained shear strength of the overconsolidated clay and the equation (4) by Yasuhara(1994), for the postcyclic shear strength were found to be relatively well applicable in the case of Kofonsolidated. It was also suggested that the value of the critical state pore pressure parameter As in these two equations for the in situ shear strength of lightly overconsolidated clay(OCR< 3) be obtained by the standard consolidating test.
