摘要
Accidents tend to happen during tunnel construction due to the harsh environmental and geological conditions. Towards high safety risk during tunnel construction, a digital-twin based multi-information intelligent early warning and safety management platform is proposed in this study. At first, a communication line is built inside tunnel through multifunctional base stations. Multi-source information from tunnel construction could be collected and transmitted automatically. Then, dynamic tunnel construction information and surrounding rock conditions are virtual simulated. Meanwhile, four-level early warning and emergency response plan are built to provide judgement on the construction status. At last, application effects of the platform are validated in a deep buried tunnel project, Dongtianshan Tunnel in China, which has extreme weather, harmful gas, and bad geological conditions. A collapse accident of tunnel excavation face was successfully predicted by the platform. Early warning and appropriate emergency measures were taken in time, and the personnel safety was ensured.
