摘要： 以青岛某跨海隧道工程为例，根据水文地质勘察资料，在详细阐明隧址区工程地质特征、地下水发育与分布规律等水文地质特征的基础上，对陆域段和海域段隧道分别建立涌水量预测模型，并进行涌水量的估算和预测，计算表明，隧道陆域段涌水量≤3.67/(m3·d-1·m-1），地下水对施工影响不大。海域段涌水量0.92~19.73/(m3·d-1·m-1），综合渗透等级为中等透水。

Abstract: This paper presents the hydrogeological survey results of a proposed crosssea tunnel in Qingdao. After a brief introduction of the hydrological features such as, site geological conditions, groundwater characterization and distributions, the groundwater inflow quantity of land portion as well cross-sea portion during the tunnel construction are estimated, respectively. The results indicate that, the estimated groundwater inflow in land portion is less than 3.67 m3/(d·m） and this quantity has negligible adverse impact on the tunnel construction. However, the groundwater inflow quantity in crosssea portion is approximately between 0.92 and 19.73 m3/(d·m）. This inflow quantity belongs to the property of medium permeable soil stratum.

Key words: Cross-sea Tunnel, Hydrogeological Characteristics, Groundwater Inflow Prediction, GroundwaterInflow Model
