To study cyclic and post cyclic monotonic axial stress behavior of fine grained soils, undisturbed soil specimens were obtained from boreholes drilled to a depth of 20m in the heavy damaged area. The plasticity index of undisturbed soils was in the range from non plastic to 40. Specimens were isotropically consolidated to 100kPa which was higher than effective geological loads. Both cyclic and monotonic tests have been conducted in triaxial test apparatus. Stress controlled dynamic tests at 0.1 Hz frequency were performed under different cyclic axial stress ratios, and following cyclic test monotonic tests were conducted on soil specimens controlling the strain rate. Cyclic axial strain history of fine grained soil varied from ε=±0.4% to 9%. The results have indicated the post cyclic monotonic strength of fine grained soils decreases by increasing cyclic axial strain level.
