Abstract

In this paper the unconfined compressive strength (UCS), the tangent and secant Young's modulus of 35 British sandstones are analysed statistically. The results of sandstones tested in the dry and saturated states were investigated and petrophysical constants derived. Although the sandstones have different mineral contents, grain size, porosity, etc., the results show the same general characteristics. The relationship between the different petrophysical constants is examined.

Résumé

La résistance à la compression simple ainsi que les modules d’Young tangent et sécant de trente cinq grès britanniques sont analysés statistiquement. Les résultats relatifs à ces grès testés en conditions sèche et humide ont été analysés et des paramètres pétrophysiques en ont été déduits. Bien que ces grès présentent des compositions minéralogiques, des tailles de grains et des porosités différentes, les résultats reflètent des caractéristiques générales semblables. Les relations entre les différents paramètres pétrophysiques sont examinées.
