Elastic behaviour of normally consolidated clay

This paper discusses the results of unloading and reloading tests performed on normally consolidated clay, under conditions of triaxial compression and extension. Based on these results, an empirical law for the stress- strain behaviour of the soil is proposed. In order to understand the elastic behaviour of soil due to shearing, drained triaxial tests are carried out by unloading and reloading the stress ratio with the mean effective stress kept constant. Then, to study the elastic behaviour of soil caused by swelling or recompression, drained triaxial tests are conducted by unloading and reloading the mean effective stress while keeping the stress ratio constant. By dividing the elastic strain of soil into two components, shearing strain and swelling (or recompression), these experimental results are analyzed and empirical law for the stress- strain behaviour of soil in the elastic region is proposed. Lastly, this paper discusses results of other experiments in which the stress ratio, etc, was decreased and the mean effective stress was increased simultaneously, under triaxial compression. These results are analyzed using the empirical law proposed in the first part of the paper (a).
