摘要
大埋深水工隧洞地质条件复杂,岩爆频发,对工程施工的安全稳定带来较大威胁。超前地质预报在预测前方工程地质和水文地质方面成为一项非常重要的研究课题。基于工程前期地质勘查资料,运用TST地震波和CFC地磁波综合物探技术预测隧洞掌子面前方100 m范围内围岩的地质情况,进而预测前方的不良地质体,包括断层破碎带、节理裂隙发育带、岩溶等情况,判定不良地质的位置、结构、规模,避免并降低地质灾害发生的风险,提出对应的预防和处理措施,可为信息化设计和下一步施工提供可靠依据。
The geological conditions of large buried deep hydraulic tunnels are complex,and rock bursts occur frequently,which poses a great threat to the safety and stability of engineering construction.Advance geological forecasting has become a very important research topic in predicting engineering geology and hydrogeology ahead.Based on the geological exploration data in the early stage of the project,the comprehensive geophysical prospecting technology of TST seismic wave and CFC geomagnetic wave is used to predict the geological condition of the surrounding rock within 100 m in front of the tunnel face.Then predict the unfavorable geological bodies in front,including fault fracture zone,joint and fissure development zone,karst,etc.,determine the location,structure and scale of unfavorable geology,and avoid and reduce the risk of geological disasters.The corresponding preventive and treatment measures are put forward,which can provide a reliable basis for the information design and the next construction.
