COMPRESSIBILITY OF CLAYS: FUNDAMENTAL AND PRACTICAL ASPECTS

Strain rate, temperature, sampling disturbance, stress path, and some restructuring factors influence the compressibility of natural clays. This paper reviews the effects of these factors, particularly strain rate and temperature, and then discusses the influence of drainage conditions on the effective stress-strain curves followed in various subelements of a consolidating clay layer. The paper also considers in-situ conditions. In the overconsolidated range, and at the preconsolidation pressure, the behavior is influenced by the previously mentioned factors, and can be compared with laboratory test results only on the basis of a semiempirical approach. In the normally consolidated range, major factors are strain rate and temperature, and their effects can be assessed. Sometimes, structuring phenomena can decrease the viscous effects. Practical conclusions regarding the evaluation of long-term settlements are provided.
