The Analysis of the Relationship between Height-diameter Ratio and Rock Uniaxial Compressive Strength

  Rock uniaxial compressive strength,one of the most important parameters of physical-mechanical properties of rock,which can reflect the hard degree of rock immediately,and height-diameter ratio can reflect rock uniaxial compressive strength as important property.When height-diameter ratio ranges from 2 ~ 2.5 ruled by national standard and ranges from 2.5 ~ 3 ruled by international standard,rock compressive strength is close to the real uniaxial compressive strength gradually.In order to exptore the specific influence from different height-diameter ratio to rock uniaxial compressive strength in detail,in this paper,we had simulation compressive tests to rock samples with different height-diameter ratio in 20 teams based on RFPA2D simulation software.Through the data acquisition,contrast,analysis,finishing,we have got the concrete changing laws of rock compressive strength followed by height-diameter ratio,thus provides powerful evidence to the researching of the hard degree of rock in practical engineering.
