Destructuring coefficient is an index that shows effect of geological history and sedimentary processes on formation of fabric and structure in fine soils. In this research, the necessary studies for determining destructuring coefficient in Kerman city deposits were done by the behavior of natural and reconstituted soils. Thus, at first, reconstituted consolidation curves for the deposits called intrinsic compression curve was extracted. For evaluating soil destructuring coefficient, three different methods which are applicable in evaluating soil destructuring coefficient were applied. Thus, the required parameters of any model were extracted and natural compression curves were compared with intrinsic compression line or curves; then soil destructuring coefficient was calculated using theoretical model. The results showed that range of structuring coefficient was less than unit and structure and fabric of soils were not developed. Also, formation of cement between the grains was not complete.
