Geotechnical seepage simulation methods and intelligent construction & maintenance technology for underground engineering
Focusing on the key theoretical challenges in the prevention and control of major sudden surge water disasters in tunnels and underground projects, the seepage disaster mode and sudden surge water mechanism of rock-groundwater system have been revealed. Meanwhile, the numerical methods for the whole process of disaster evolution of rock-groundwater system have been performed and the disaster analysis software HazE has been independently developed, after which the risk warning and control technology of water surge disasters have been established. The difficulty of disaster mechanism, as well as the early warning for disaster prevention and control, has been solved. The decision-making level of disaster prevention has then been scientifically improved.
In view of the pressing demand of unmanned construction of tunnels under extreme environment and extreme geological conditions, two major robot systems have been proposed for drill-blast method tunnelling auxiliary and constructions, which has gradually been applied to a major railroad tunnel in southwest China; The "five senses and one brain" equipment system has been developed and successfully installed into the "Smart One" shield machine and launched in Jinan Metro Line 6; The multi-process anchor boring machine for small section tunnel has been developed and applied in the water diversion project in central Yunnan.
To solve the challenge of accurate detection and efficient diagnosis and treatment of operational tunnels, a high-speed information collection and accurate extraction technology integrating "laser-vision-radar" has been proposed and an intelligent detecting robot for multiple types of diseases in the whole area has been developed. A scientific decision-making method for disease remediation has been proposed, after which intelligent robots for efficient disease remediation and synergistic matching repair materials have been developed to achieve rapid targeted repair of diseases.
