The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...

Get price2013-3-13 · Intact rock strength (IRS) is a major rock property. Intact rock strength determines the strength of the intact rock block material and as such governs partially the strength of a rock mass. Standard determination of the IRS is by means of a unconfined compressive strength (UCS) test. In, for example, most rock mass

Get priceIntroduction Uniaxial compressive strength (UCS) is one of the most widely used rock mechanical parameters in rock engineering like design and construction of foundations, tunneling, slope stability investigations, etc. UCS is also the only parameter to assess rock material strength in Rock Mass Rating (RMR) proposed by Bieniawski (1989).

Hoek and Brown compiled extensive data on a variety of rock types and produced relationships that are simple and can be developed into forms amenable to well-log analysis. A primary feature of this failure criterion is a relation between the maximum and minimum stresses when both are normalized by the uniaxial compressive strength
