Abstract
Although NATM is widely applied in modern tunnel design and construction, tunnel construction is still deemed highly risky due to the unknown ground condition ahead of the excavation face. Faults, massive groundwater, fracture zones, and other factors might easily cause great danger to the excavation work. To enhance the safety management of NATM, the tunnel seismic prediction (TSP) method is introduced to help detect unstable ground conditions to prevent the happening of collapses or disasters during tunnel excavation. With the reflected seismic waves collected from several explosions, TSP could produce high-resolution simulated images that, with careful interpretation, will reveal the ground conditions ahead. In this paper, how TSP is incorporated with NATM for better construction safety is presented.
