摘　　要：地铁隧道施工期间,相当有必要进行超前地质预报。以广州市轨道交通21号线为例,介绍了城市地铁隧道超前地质预报的技术方案,以及超前预报在地铁隧道和铁路山岭隧道中工作开展的区别,同时对典型预报案例进行分析,并与隧道后期开挖揭示情况进行了对比。结果表明,超前地质预报在城市地铁隧道中取得了较好的预报效果。During the construction of the subway tunnel, it is necessary to carry out advanced geological prediction. This paper introduces the technical plan for advanced geological prediction of urban subway tunnel with Guangzhou rail transit line 21 as an example. Besides, it also introduces the difference between the advanced geological prediction in subway tunnel and in railway mountain tunnel. At the same time, through the analysis of the typical prediction case and the comparison with the revealing of the tunnel excavation in the later period, it is verified that the geological forecast has achieved good prediction effect in urban subway tunnel.
