摘　　要：隧道施工过程中开展超前地质预报,对掌子面前方地质环境进行探测预报,对准确预报不良地质体的位置,指导提前做好相应的应对措施减小风险灾害发生的概率有极其重要的意义。文章以实际工程为依托,针对围岩富水裂隙带,总结出有针对性的探测反映特征,与实际工程开挖情况进行对比验证其可靠性。为今后类似的隧道工程超前地质预报工作提供参考。In the process of tunnel construction,it is of great significance to carry out advanced geological forecast,to detect and forecast the geological environment in front of the palm surface,to accurately predict the location of bad geological bodies,and to guide the corresponding countermeasures in advance to reduce the probability of risk and disaster.Based on the actual project,aiming at the water rich fracture zone of surrounding rock,the paper summarizes the targeted detection reflection characteristics,and verifies its reliability by comparing with the actual engineering excavation situation.It provides a reference for similar tunnel engineering geological prediction in the future.
