Rock Strength an overview ScienceDirect Topics

Rock strength and porosity have good correlations for various rocks, and porosity can be obtained from lab tests or from density and sonic logs. In the following equations, the rock strength UCS is in MPa and porosity is in percent (%). For shales in the North Sea (geologically young and weak shales, mostly high-porosity Tertiary shales), Horsrud (2001) proposed the following correlations for

Compressive strength of rocks PetroWiki

Jun 04, 2015· Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but

Rock Thermal properties Britannica

Rock Rock Thermal properties: Heat flow (or flux), q, in the Earth’s crust or in rock as a building material, is the product of the temperature gradient (change in temperature per unit distance) and the material’s thermal conductivity (k, the heat flow across a surface per unit area per unit time when a temperature difference exists in unit length perpendicular to the surface).

DIFFERENT TYPES OF WEATHERING OF ROCK MASS

It is not a method for describing the engineering properties of a rock mass. As such, describing the state of weathering must never be a substitute for an adequate description of the intrinsic physical/mechanical properties of a rock mass using the standard descriptors set out in this guideline (e.g. strength, defects, fabric, rock type).
