摘要
在隧道开挖过程中,超前地质预报已成为准确预报隧道前方围岩地质情况的有效方法,其中TSP法是较为成熟、直接的预报方法。结合凤凰岭隧道实体工程,采用TSP地震预报法,对隧道施工过程的断层破碎带、塌方、软岩和水进行了较为精准的超前预报,为确定合理的隧道开挖支护方案提供技术支持。
In the process of tunnel excavation,the advanced geological forecast has become an effective method to accurately forecast the geological situation of the surrounding rocks in front of the tunnel,among which the TSP method is a more mature and direct method.According to the solid project of Fenghuangling Tunnel,the TSP earthquake forecast method is adopted to accurately forecast the fault fracture zone,collapse,soft rock,and water in the tunnel construction,which provides technical support for determining reasonable tunnel excavation and support schemes.
