Abstract:In underground engineering, tunnels are important passages for underground wastewater, personnel and vehicles. As the surrounding rock usually experiences the splitting failure, the mechanical properties of the rock subjected to splitting loading are important for surrounding rock stability after a fire. In this study, Brazilian splitting tests were carried out on sandstone after different temperatures (25 °C to 1000 °C), and the acoustic emission (AE) signals of the rock splitting failure process were obtaine… Show more
