REAL-TIME MONITORING AND EARLY WARNING METHOD OF DISASTER PRECURSOR INDUCED BY SERIOUS WATER INRUSH IN UNDERGROUND ENGINEERING

摘要

A real-time monitoring and early warning method is proposed to monitor and disaster precursor induced by serious water inrush. Four types of water inrush are put forward, including type of fracture, type of fault, karst cave and cavity, channels and underground rivers. On the basis of experiment and engineering, we divide the pregnant disaster model into three types: instant explosion type, strong filling-lagging type and weak filling-intermittent type. Two real-time monitoring methods of water inrush and mud resistance structure failure are aim at solving the program of two water inrush types: water-resisting rock mass fracturing water inrush and filling medium infiltration and instability water inrush. A water inrush disaster remote monitoring and early warning analysis system is established, this analysis system can be further used for railway tunnels and highway tunnel engineering.
