Abstract

In order to reveal the influence of friction between loading plate and test piece on test strength, Alloy steel, polytetrafluoroethylene and rubber are used as cushion, Uniaxial compression tests of marble cubes under different end contact conditions were carried out. The test results show that, When the cushion is thick, the greater the cushion stiffness is, the greater the test strength is; when the deformation modulus of cushion material is significantly smaller than the tested piece, the greater the cushion thickness is, the lower the test strength is,so the characteristics of cushion have significant influence on the test strength and failure characteristics. Based on the transverse deformation capacity of loading plate and specimen, the influence rule of different end conditions on test strength is given. The comparative test is carried out with a cylinder sample with a height diameter ratio of 2.0, Based on the viewpoint of relative strength, a new idea of reducing friction in rock test is put forward.
