    Abstract

    It is now well recognized that the presence of carbonate material in submarine soils often affects their engineering behavior significantly because of (1) crushing of carbonate particles under stress and (2) cementation by carbonate material. This paper shows that depending on the nature of carbonate material, the magnitude of crushing and degree of cementation both vary over a wide range and have a markedly different influence on engineering behavior of carbonate soils. Existing classification systems do not take adequate note of this fact and hence are not totally satisfactory from an engineering viewpoint. A system of description is proposed for carbonate soils which, it is hoped, will in due course provide information to evolve a useful engineering classification system.
