Evaluation of simple methods for assessing the uniaxial ...

Rock engineers widely use the uniaxial compressive strength (UCS) of rock in designing surface and underground structures. The procedure for measuring this rock strength has been standardised by both the American Society for Testing and Materials (ASTM) [1] and the International Society for Rock Mechanics (ISRM) [2] .

Compressive strength of rocks

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 many ...
