Some observations regarding the strength and deformability of sandstones in dry and saturated conditions

摘要

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.
