| 内容記述 | In order to investigate the environmental dependence on strength of rock, uniaxial compression test and Brazilian test under water vapor environment were conducted on Kumamoto andesite and Kitagishima granite. Tests were carried out under various water vapor pressures, which are controlled in special chambers, at a constant strain rate. The results obtained by the uniaxial compression test and Brazilian test are follows: The Young's moduli are almost constant with the change of water vapor pressure. On the other hand, the water vapor pressure largely affects the uniaxial compressive strength and the tensile strength of rock. Namely, the strengths of rock increase with decreasing water vapor pressure. The relationships between uniaxial compressive strength Sc , tensile strength St and water vapor pressure p can be represents by the following equation: long Sc ∝ -Nc log p and long St ∝ -Nt log p, where Nc and Nt are the inclination of lines. Comparing the above equations based on the test results with equation (5), the stress corrosion indexes are obtained as 24 in Kumamoto andesite and 62 in Kitagishima granite on uniaxial compression test, then 58 in Kumamoto andesite on Brazilian test. It is discussed that the difference between the stress corrosion indexes obtained from uniaxial compression test and Brazilian test is caused by the stress state within rock specimen in each test. The estimation method of long term-strength of rock is shown according to equation (8), then the long-term strength of Kumamoto andesite and Kitagishima granite can be estimated concretely, that is, uniaxial compressive strengths of Kumamoto andesite and Kitagishima granite after 1000 years are estimated 75% and 89% of uniaxial compressive strengths at the present time respectively. |
