Abstract: The geological conditions encountered in the construction of the Changshan Tunnel of Huashan Boulevard in Wuhan are characterized by Karst Geology and a fractured rock mass. These unfavorable geological conditions might adversely affect construction. This paper presents the application of a geological condition prediction technology: Tunnel Seismic Prediction (TSP) in the tunnel excavation. The TSP successfully predicted the karst rock cavities with groundwater between Station K3+180 and K3+144; the fractured rock mass zone between Station K3+144 and K3+114 is also detected before the excavation.

Key words: Unfavorable Geologic Conditions, Advanced Geological Forecast, Tunnel Seismic Prediction, Karst Formations, Fractured Rock Mass Zone
