摘　　要：在隧道施工过程中,隧道前方岩溶发育情况不清楚,地质构造复杂,岩体破碎情况不明确。为了确保施工安全,减少和避免地质灾害发生,人们可以采用TST技术对隧道进行超前预报。结果表明,TST技术有效地提高了分析精度和构造定位精度,消除了侧向回波和面波,成功地解决了断层、破碎带及含水带的超前地质预报问题,因此该技术可以广泛应用于隧道施工地质灾害的预报中。During the construction of the tunnel,the development of the karst in front of the tunnel is unclear,the geological structure is complex,and the rock fragmentation is unclear.In order to ensure construction safety,reduce and avoid the occurrence of geological hazards,people can use TST technology to forecast the tunnel in advance.The results show that TST technology effectively improves the analysis accuracy and tectonic positioning accuracy,eliminates lateral echoes and surface waves,and successfully solves the problem of advanced geological prediction of faults,fractured zones and water-bearing zones.Therefore,this technology can be widely used in the prediction of tunnel construction geological hazards.
