摘　　要：地质信息采集、超前预报与数据解译是隧道超前地质预报中的3个重要环节,首先讨论了超前开挖隧道的地质编录的工作方法,包括风险靶段分级、掌子面地质素描,进而绘制平面地质图,建立三维地质模型,计算不良地质体及含水体在相邻未开挖隧道的出露位置。在此基础上,详细讨论了仪器配合的关键问题,并开发了隧道超前地质预报自动选择程序,可以帮助操作员从中选择不同岩性地区、不同构造发育特点、不同地下水文条件下需要选择的预报方法,并建议了特殊地段的预报方法选择,最后结合工程实例讨论了几种常用的预报方法的数据解译过程中应注意的问题及典型不良地质体的判据。其结果对于隧道超前地质预报工作具有一定的借鉴与指导意义。Geological information acquisition, geophysical prediction and data interpretation are three major links of tunnel geological prediction. In this article the methods of geological logging were firstly discussed, including tunnel risk classification, geological sketching on tunnel face, then the geological plane map was plotted and the three-dimensional geological model was built. The location of the defective geological karst-fractured groundwater in adjacent tunnel could be calculated from the geological model Based on this situation the key issues of instruments were discussed in detail, and developed the tunnel geological prediction automatic selection system, which could help the operators choose proper methods for zones with different rock characters, structure development characters and underground hydrological features, and make suggestion for special geological zones. At last the criterions on data analysis of staple prediction methods of typical adverse geological bodies were given, which had a certain reference to tunnel advanced geological prediction.
