This research was performed to determine the efficiency effect of sedimentary environment of Kerman City area on soil structure bycomparing natural and reconstituted consolidation curves. In this regard, four different criteria such as sensitivity strength, stresssensitivity, Schmertman criteria and the result of the uniaxial compression test were used. The base of these criteria is to compare theresults of natural and undisturbed soil consolidation tests. The position of undrained shear strength of Kerman City soils in Iv-Su spacewas located on the left side of the intrinsic strength line and this confirms that the stress sensitivity of soils is less than the unit.Therefore, the soils in the city subzone are mostly over consolidated, and cementation and chemical bonds have not developed. Theswelling sensitivity of fine grained soils based on Schmertman criteria are often less than 2 or slightly larger than 2.5 indicating that thesoils of Kerman City subzones have underdeveloped swelling sensitivity due to poor cementation.
