摘　　要：针对复杂水文地质条件的地铁区间隧道联络通道涌水风险,引入声纳渗流技术探测联络通道区域内地下渗流场特征,采用三维流速矢量声纳测量仪分别进行洞内无损探测和地表井孔测量,综合判断探测区域内的渗流场分布规律。研究结果表明:声纳渗流技术可以在水文地质勘察和涌水渗漏治理中应用,快速准确地测量渗水路径、补给来源以及流速、流向、流量、渗透系数等量化指标,以此建立地下渗流场三维可视化云图,科学指导工程降水设计、涌水渗漏处理,并能验证注浆堵漏处理效果,提前防控暗挖隧道涌水渗漏风险,可为类似工程的安全风险管控提供借鉴和参考。Aiming at the risk of water inflow in the connecting passage of metro tunnel under the complex hydrogeological conditions,the sonar seepage technology was introduced to detect the characteristic of underground seepage field in the area of connecting passage.The internal non-destructive detection and ground surface borehole measurement were carried out respectively by using the three-dimensional flow velocity vector sonar detecting instrument,and the distribution laws of seepage field in the detection area were judged comprehensively.The results showed that the sonar seepage technology can be used in the hydrogeological investigation and the water inflow and leakage treatment.The seepage path,supply source and quantitative indexes such as flow velocity,flow direction,flow rate and permeability coefficient can be measured quickly and accurately,thus the three-dimensional visualized cloud map of underground seepage field can be established,so as to scientifically guide the engineering dewatering design and the water inflow and leakage treatment.Meanwhile,the effect of grouting plugging treatment can be verified to prevent and control the risk of water inflow and leakage of the concealed excavation tunnel in advance.It can provide the reference for the safety risk control of similar engineering.
