In this paper, the correlation between different groundwater in the study area is analyzed by using the hydrological data from the hydrogeological test holes and the long-term observation holes based on the hydrogeological data between the Jinggangshan Road Station and the Jianianhua Station on the Qingdao Subway Line R3. The conclusions are as follows. When the drills are near the seashore(less than 50m) and the backfilled formation has a large permeability coefficient(the backfilled components being coarse particles), the Quaternary pore water is connected with the seawater and there is correlation between the two. When the drills are far from the seashore(more than 50m) or the backfilled formation has a small permeability coefficient, there is no correlation between the two. When the drills are near the seashore(less than 50 m) with developed bedrock fissure, the bedrock fissure water is connected with the seawater and there is correlation between the two. When the drills are far from the seashore(more than 50m), or when the bedrock fissure is undeveloped, there is no correlation between the two. There exists an aquifer(mainly marine muddy silt clay layers and partially silt clay layers) between the Quaternary pore water and the bedrock fissure water, which blocks the connectivity between the two. Consequently, there is no correlation.
