抄録

Uniaxial and indirect tensile strength of Sanjome andesite was obtained under air-dried and water-saturated conditions. It was found that the strength increases with loading rate in both conditions.<BR>The difference in loading-rate dependency can not be observed between uniaxial and indirect tensile tests. And also the amount of strength increase with ten fold increase of loading rate shows no difference between air-dried and watersaturated conditions.<BR>The experimental results were compared with previous results of uniaxial compressive strength. And, it was found that all results can be approximated by an equation where S is strength when loading time upto strength failure is tF, S0 is strength when loading time is 500s, S0 DRY is S0, in air-dried condition, δ' is a constant.
