COMPREHENSIVE DETECTION SYSTEM OF GEOLOGICAL PRECURSORY CHARACTERISTICS FOR ROCK BURSK AND WATER INRUSH
Both rock burst and water inrush are serious geological hazards in deep underground engineering, and it happened frequently in the excavation of auxiliary tunnel of Jinping Hydropower Station in China. Great damage to constructions was often caused by the geological calamities. In order to predict and control these geological hazards, a comprehensive detection system of geological precursory characteristics was established. It was proved that development degree of joint fissures was an important geological precursory characteristic, and mechanical parameters were gained by means of elastic wave techniques. According to the development characteristics of joint fractures and mechanical datum, good conclusions can be drawn about geomechanics failure patterns of rock burst, transmitting and bearing structures of water, and failure patterns of rock mass . This system reduced risk of rock burst and water inrush effectively. Finally, case studies had also been done.
