摘要： 武汉花山大道长山隧道不良地质段主要表现为岩溶和破碎地质带，给施工带来了相当的难度。为赢得时间，利用TSP超前地质预报技术，对不良地质段做了超前预报，探测表明在K3+180～K3+144段发育有溶洞并伴有少量裂隙水，K3+144～K3+114段为破碎地质带。实际地质情况与预报结果吻合较好，为隧道施工方案和施工措施的选择提供了重要的参考依据。

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
