Virgin compression of structured soils

This paper describes a study of the virgin compression behaviour of both naturally and artificially structured soils under one-dimensional compression or isotropic compression. It is proposed that during virgin compression, the additional voids ratio sustained by soil structure is inversely proportional to the current mean effective stress. The proposed formula has been verified for 20 different naturally and artificially structured soils, and it is seen that the proposal describes well the behaviour of all these soils. Finally, a general discussion on soil structure and its features is presented, and the proposed compression equation is extended to describe the compression of structured soil along a general stress path. Cet exposa est une etude du comportement d'une consolidation vierge sur des sols structuras de mani&gravere naturelle et artificielle, avec une consolidation unidimensionnelle on isotrope. Nous avancons que pendant la consolidation vierge, le taux de pore additionnel subi pa...
