摘　　要：为了对隧道不良地质体施工提供安全保障,开展以地震波反射法为主要手段的综合超前地质预报。结合工程地质调查和掌子面地质素描,采用TSP203^(plus)进行长距离预报,同时运用超前水平钻探进行更为精确的短距离预报和加深炮孔对大范围不良地质体进行跟踪预报。该预报方法应用于金瓶岩隧道软弱破碎带和富水带,取得良好效果,有效指导了隧道安全施工,可为同类工程提供借鉴。In order to provide security for unfavorable geological body,the comprehensive advanced geological forecast is carried out,in which the seismic wave reflection method is the main way.According to the engineering geological survey and geological sketch of tunnel face,long-distance forecast is carried out by means of the TSP203 plus geological forecast system.Meanwhile,the advanced geological drilling and the deepening blast hole method are also applied for short-distance prediction more accurately.The forecast method has been applied in water-rich and fractured weak fault zone of Jinpingyan Tunnel,and the forecast results obtained from the proposed method are generally in a good agreement with the field-observed results.The comprehensive advanced geological forecast technology has provided a powerful tool for systematically forecasting the geological disaster in the process of tunnel construction.
