General report, session I: Engineering properties of carbonate rocks
Abstract After reviewing the geological classification of carbonate rocks, a method of describing carbonate rocks for engineering purposes is developed following the recommendations set out by the I.A.E.G. Mapping Commission. Particular attention is paid to the details of the weathering profile developed on carbonate rocks. The engineering classification of carbonate rocks is based on both the engineering behaviour of the rock as a material and in the mass. Physical properties, including strength and deformation characteristics, are used to determine a modulus ratio for a wide range of limestones including the English chalk. In addition to rock material properties, and engineering classification of the rock mass has to take account of structure, discontinuities, and details of the weathering profile. Assessment of rock mass properties requiresin situ testing to determine deformation characteristics. If the usually limited amount of data on such quantitativein situ properties is related to other measures of rock quality, then engineering geological mapping can be used to extend the applicability of the limitedin situ data to a whole site. RQD has been related to the compressibility of the rock mass, and a rock mass factor has been proposed that links the deformability of the rock material to that of the rock mass. Rock mass classifications for large underground openings may be used with limestones. Engineering problems associated with carbonate rocks are briefly reviewed, as are the properties of limestones as a building stone and as aggregate.
