Abstract:
This paper presents the results of uniaxial compressive and tensile test for two different kind of granites. The test were conducted by the complex liquid-gas pressure system under the loading rate from 1 × 10-1 (kg · cm-2) · s-1 to 1 × 10
5(kg · cm-2) · s-1. The results of test show that compressive and tensile failure strength of rocks notably increase with the rate of loading of specimens. Also, the strength ratio of compression-tension of rocks is not a constant. It increase slightly with the loading rate.
