摘要： 隧道施工特别是复杂地质条件下的施工面临着许多地质灾害问题，如强风化砂岩、断层破碎带的塌方等。准确地进行隧道超前预报，能有效降低施工风险，确保施工安全和进度，减少工程事故的发生。针对湖北宜巴高速公路付家冲强风化砂岩隧道工程，利用TSP超前地质预报技术，并结合隧道工程地质情况，阐述了TSP超前地质预报的基本原理和方法，探讨了该技术的应用效果，并将预报结果与实际工程进行对比，验证了该技术的可靠性。

Abstract: There are many geological hazard accidents in the tunnel construction especially under the condition of complex geology, such as the strong weathered sandstone and the landslip of the faulted fracture zone. The construction risk is reduced effectively, the construction security and the progress are guaranteed and the project accident's occurrence is reduced by the accurate advanced geological forecast. According to Fujiachong tunnel engineering of Yiba highway in Hubei province, based on the TSP advanced geological forecast, its basic principle and method are introduced and its application is evaluated. The result is proved during the construction, which indicates its reliability.
