Relationships between Mechanical Properties of Granites, Korea

국내(國內) 화강암(花崗巖)의 역학적(力學的) 성질간(性質間)의 상관성(相關性)

Extensive sets of data on the mechanical properties of more than 1000 granite specimens were analyzed to derive the relationships of the various properties: those are, (1) density, (2) porosity, (3) absorption ratio, (4) sonic wave velocity, (5) uniaxial compressive strength, (6) tensile strength, and (7) dynamic & static Young's moduli. The results will be of use to understand the mechanical characteristics of granites and some unknown properties can be estimated from the others. The various equations derived from the least square regression analysis and a brief description of the correlations are presented in this paper.
