摘　　要：隧道建设对于完善我国道路基础设施具有关键作用,在地质环境复杂的区域进行隧道建设极易受到断层、岩溶等情况的影响,严重威胁隧道施工安全及施工质量。基于此,研究综合物探方法在隧道地质超前预报中的应用,分析了隧道地质灾害的常见类型及预报方法,结合各物探法的特点对隧道工程应用进行分析,提出将TSP法、探地雷达法及瞬变电磁法三种方式相结合开展综合物探,从探测深度、预测精度、适用范围等方面互补。结果表明,超前预报结果与实际情况基本相符。Tunnel construction plays a key role in improving road infrastructure in China.Tunnel construction in complex geological environment is easily affected by fault,Karst and other conditions,which seriously threatens the safety and quality of tunnel construction.Based on this,the study analyzes the application of comprehensive geophysical exploration method in the advance prediction of tunnel geology,the common types and prediction methods of tunnel geological hazards,and the tunnel engineering application in combination with the characteristics of each geophysical exploration method.The study proposes to conduct comprehensive geophysical exploration in the combination of TSP method,ground penetrating radar method and transient electromagnetic method;and complements from the depth of detection,prediction accuracy,and application range,etc.The results show that the advanced prediction results are basically consistent with the actual situation.
