heal.abstract	This paper investigates structure development and degradation in natural soils and weak rocks and their effects on the compressibility and shear strength. 'Structured' states are contrasted to 'intrinsic' states in an attempt to include over-consolidated clays among the structured soils and study them within the proposed framework (with bond strength controlled by the maximum pre-consolidation pressure). The proposed framework is used to interpret the position of in-situ material states in the e-p' space depending on the type and the time of structure development. The onset of plastic strains where structure degradation is initiated, is distinguished from the condition where an abrupt loss in stiffness is observed indicating structure degradation at appreciable rate. The proposed framework is applied in the interpretation of the in-situ states and the mechanical behaviour of the Corinth marl, a stiff calcareous cemented soil from Greece.	en
