【摘要】 基于岩溶隧道施工中易发生突水、突泥(涌砂)和塌方等安全事故,造成人员伤亡、经济损失和隧址区水文地质环境破坏等情况,依据不同超前地质预报方法优缺点和适用范围,提出了针对突水、突泥、断层破碎带、岩溶、围岩类别及稳定性的综合超前地质预报方法,建立了宏观超前地质预报、长期超前地质预报、短期超前地质预报、地质灾害临近预报的多步预警预报体系,预报体系在沪蓉西高速齐岳山隧道等工程中得到了成功应用.更多还原

【Abstract】 Engineering geological and hydro-geological conditions are highly changing and complex in karst developing district of tunnels.Water inrush,mad(sand) flush,collapse and some other geological hazards often occur in the construction of karst tunnels,which often bring about great casualties,economic losses and environmental destruction of karst hydrogeology. According to the applicable scope,merits and drawbacks of different geological prediction methods,an integrated advanced geological prediction methods was put forth to predict water inrush,mad flush,fault fracture zones,karst classification and stability analysis of rock mass.A multi-step warning and prediction system was established,which included macroscopic,long-term,short-term geological prediction methods and geological precursory prediction methods.The multi-step warning and prediction system was successfully applied in the construction of the Qiyueshan Tunnel and others.更多还原
