Evolution of mechanical properties of granite at high temperature and high pressure

Rock engineering works, such as geothermal and deep hydrocarbon resource development and deep underground geological disposal of nuclear waste, are closely related to the mechanical properties of rocks at high temperature and high pressure. This study reports on the use of the micro-CT technique, acoustic emission (AE) technique and the 600 °C 20MN servo-controlled trixial compression system for rock testing under high temperature and high...
