YIELDING OF MEXICO CITY CLAY AND OTHER NATURAL CLAYS

A series of triaxial tests was conducted on a typical Mexico City clay using a variety of stress paths to define the yield curve of this soil, namely clays of extremely high friction angle. This yield curve, together with other curves from the literature, gave information for clays with friction angles in the normally consolidated range between 17.5 deg and 43 deg, allowing a generalization of the concept. The paper also discusses the coefficient of earth pressure at rest in the normally consolidated ranges. The details of the testing program are described. The data gathered showed that a yield curve can be established for Mexico City clay. Its shape is very similar to those obtained from other natural clays and reflects the stress anisotropy of the clay during its deposition.
