摘　　要：主要针对隧道施工过程中采用的地震超前预报方法进行了阐述,重点介绍了TST超前地质预报技术。负视速度法、HSP方法、TSP方法、TGP方法、TRT方法和TST方法各有其优缺点,从预报的效果来讲,TST方法满足准确预报的5个条件,但由于其操作比较复杂,时间成本较高,难以推广应用,可以在复杂地质条件下进行局部应用。隧道超前预报应采用综合预报方法,物探方法、电磁方法和地质调查紧密联系,尤为重要的是要重视地质分析,掌握地层的分布规律,了解地质构造的特征,才能使得结果解译更加准确合理。In this paper,the earthquake prediction method used in tunnel construction is described,and emphatically introduced the TST advanced geological prediction technology.Each prediction method has the advantages and disadvantages,these methods include Negative apparent velocity,HSP,TSP,TGP,TRT and TST.From the effect of prediction,the TST method can meet the five condition of accurate prediction,but because of its complexity,high time cost,it is difficult to be applied,and can be used in the complex geological conditions.In order to make the accurate and reasonable result,the tunnel advanced prediction should be based on the comprehensive forecasting method,which makes the geophysical prospecting method,the electromagnetic method and the geological investigation closely linked.It is important to pay more attention to the geological analysis,to grasp the distribution strata regularity,and to understand the characteristics of the geological structure.
