Geotechnical Soil & Rock Testing Southern Testing

Measurement of Uniaxial Compressive Strength; UCS: ISRM Part 1 2007 The rock/soil strength is determined from a uniaxial compressive strength on a cylindrical specimen. Often used to assess the strength of rock for foundation design. The strength can also be used on the stability of rock slopes and underground openings.

USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL

Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting. In order to estimate uniaxial compressive strength, index-to-strength conversion factors are used.

8. STRENGTH OF SOILS AND ROCKS

The tensile strength of soil is very low or negligible and in most analyses it is considered to be zero. In contrast a number of direct or indirect tensile strength tests are commonly carried out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force.
