Strength and Deformation Properties of Tertiary Clay at Moesgaard Museum

The tertiary clay at Moesgaard Museum near Aarhus in the eastern part of Jutland in Denmark is a highly plastic, glacially disturbed nappe of Viborg Clay. The clay is characterised as a swelling soil, which could lead to damaging of the building due to additional heave of the soil. To take this characteristic, as well as the strength and deformation properties, into account during the design phase, two consolidation tests and one triaxial test have been conducted. This paper evaluates the results of the laboratory tests leading to the preconsolidation stress, the deformation parameters consisting of the swelling pressure, the constrained modulus and the compression index, and the strength parameters comprising the undrained shear strength, the drained shear strength and the effective angle of internal friction
