Abstract

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 50 m) 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 50 m) 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 50 m), 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.

青岛地铁R3线不同地下水供应关系研究

本文根据青岛地铁R3线井冈山路站至嘉年华站的水文地质资料，利用水文地质试验孔和长期观测孔的水文地质数据，分析了研究区不同地下水之间的相关性。结论如下。当钻机靠近海岸（小于50m），回填地层渗透系数大（回填成分为粗颗粒）时，第四系孔隙水与海水相通，二者存在相关性。当钻机远离海岸（超过50m）或回填地层的渗透系数较小时，两者之间没有相关性。当钻机靠近基岩裂隙发育的海岸（小于50m）时，基岩裂隙水与海水相通，两者之间存在相关性。当钻机远离海岸（超过50米）或基岩裂隙不发育时，两者之间没有相关性。第四系孔隙水与基岩裂隙水之间存在含水层（主要为海相淤泥质粉质粘土层，部分为粉质粘土），阻断了两者的连通性。因此，不存在相关性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
