摘　　要：Advanced geological prediction is a crucial means to ensure safety and efficiency in tunnel construction.However,diff erent advanced geological forecasting methods have their own limitations,resulting in poor detection accuracy.Using multiple methods to carry out a comprehensive evaluation can eff ectively improve the accuracy of advanced geological prediction results.In this study,geological information is combined with the detection results of geophysical methods,including transient electromagnetic,induced polarization,and tunnel seismic prediction,to establish a comprehensive analysis method of adverse geology.First,the possible main adverse geological problems are determined according to the geological information.Subsequently,various physical parameters of the rock mass in front of the tunnel face can then be derived on the basis of multisource geophysical data.Finally,based on the analysis results of geological information,the multisource data fusion algorithm is used to determine the type,location,and scale of adverse geology.The advanced geological prediction results that can provide eff ective guidance for tunnel construction can then be obtained.超前地质预报是保证隧道安全高效施工的重要手段。然而,不同的超前地质预报方法都有其局限性,导致最终探测精度存在不足。采用多种方法进行综合评判,可以有效提高超前地质预报结果的准确性。本研究将地质信息与地球物理方法的探测结果相结合,包括瞬态电磁、激发极化和隧道地震波探测,以建立一种不良地质综合分析方法。首先,根据地质信息确定可能存在的主要不良地质问题。随后,根据多源地球物理数据推导出隧道掌子面前方岩体的各种物理参数。最后,基于地质信息的分析结果,采用多源数据综合分析方法确定不良地质的类型、位置和规模等,进而获得超前地质预报结果,为隧道施工提供有效的指导。
