Outline of Final Research Achievements

In order to consider the heat radiation from high-level radioactive waste or underground development of energy resources under high temperature environment, it is an important issue to evaluate the effects of temperature on time-dependent
behavior of surrounding rocks. In this research, uniaxial compressive creep tests are conducted under high temperature and high stress level compared with the uniaxial compressive strength conditions. By using tuffaceous rock and mudstone, heat accelerated creep phenomena are observed in each specimens. And the equivalent time related to temperature phenomena are also emerged in the experiments.
