| Research Abstract |
Long-term integrity is required for structures in a rock mass. Specifically, low permeability condition of rock is necessary for repositories of radioactive wastes and caverns to store liquefied petroleum gas or natural gas. In this study, I have tried to investigate the improvement of mechanical properties such as strength and permeability for rock-like materials (rock and cementitious materal) using fracture closure phenomena occurred in a condition observed in underground environment. Consequently, I could obtain some results of improvement of mechanical properties by fracture closure in rock-like materials.
