·Compressive strength is the most widely used design parameter in the construction industry and in rock engineering For example Bieniawski [Bieniawski Z T Estimating the strength of rock materials Is J S Afr Inst Min Metall 1974 74 312 320 ] reported that mining engineers request the uniaxial compressive strength UCS more often
·Compressive and tensile strengths are important mechanical properties of rock and are control parameters for the safety and stability analysis of a structure in the rock mass First this paper selected extensive rock data to study the relationship between compressive strength or tensile strength and cohesion and internal friction angle Then the relationship
· Relations between M R ρ σ c and E Figure 2 shows how uniaxial compressive strength influences the elastic modulus and the value of M R = E/σ c for all 68 studied samples From Fig 2 it is clear that the elastic modulus is partly related to uniaxial compressive strength with small R 2 = Figure 2 also demonstrates that an increase in
·Aufmuth 1973 obtained a good correlation between Schmidt hardness H R and both unconfined compressive strength UCS and tangent modulus of rock E including the effect of rock density Singh et al 1983 based on the results of sedimentary rocks developed a very simple and good relationship between UCS of rock and H R O Rourke 1989 obtained a
·In Geotechnical Engineering determining the Unconfined Compressive Strength UCS of rock is of prime importance as their role in design and analysis of geotechnical problems is crucial Although laboratory test is the most direct way for estimating the rock compressive strength but UCS determination in the laboratory would be problematic if the rock masses are
·The effect of exposure to high temperature on rock strength is a topic of interest in many engineering fields In general rock strength is known to decrease as temperature increases The most common test used to evaluate the rock strength is the uniaxial compressive strength test UCS It can only be carried out in laboratory and presents some limitations in
