This paper describes the geotechnical properties of normally consolidated Fao clay distributed at the mouth of the Shatt Al-Arab in southern Iraq.From test results, the following important geotechnical characteristics of Fao clay were obtained. Fao clay is seriously disturbed in structure by 1) the stress release during sampling and 2) the redistribution of water in the sample during sampling and trimming. The effect of the latter is considerably greater than that of the former. However, the undisturbed structure in the field may be restored when the sample is reconsolidated under the same stresses it carried in the field. To ensure the complete restoration, consolidation loads must be applied in small increments.The paper also describes the following geotechnical properties of this clay : 1) determination of the undrained strength for practical purposes, 2) anisotropy in strength, 3) strength decrease due to rebound and 4) consolidation characteristics.
