Stress sensitivity is an index that shows effect of geological history and sedimentary basin on the formation of fabric and structure in fine soils. In this research, the necessary studies for determining stress sensitivity in deposits of city of Kerman deposits were done by comparing behavior of natural and reconstituted soils. Thus, initially, undisturbed soil samples were mixed with high moisture content between 1.25 and 1.5 times of their liquid limit and, using the results of reconstituted soil consolidation tests, intrinsic compression line of city of Kerman sediments (Kerman city-ICL) was extracted. Then, some of co-sensitivity intrinsic compression lines were drawn on Iv-Log(σ`v) space. For evaluating soil sensitivity, the proposed method which was more applicable in this subject was used [29, 34] In this model, comparison of natural sedimentation compression curves with the intrinsic compression line of Kerman sediments (Kerman city-ICL) was done; then, the required model parameters were extracted and stress sensitivity index was calculated for every sample. Comparison of the results showed that range of stress sensitivity in Kerman deposits was less than unit; therefore, it can be concluded that soil structure and fabric did not superabundantly develop and probably effect of sedimentary model caused compression and over-consolidation phenomena to be more predominant than fabric and structure.
