摘要
青岛市大规模的城市建设亟需高效合理的地下空间开发。摸清青岛市地下空间地质结构特征,为城市地下空间的合理规划和开发提供更科学、可靠的依据,是实现城市可持续发展的重要途径。本文基于城市地质调查实测数据和收集的工程地质勘察数据资料,对青岛区域构造、地貌、断裂、岩土体结构及工程地质条件等梳理总结,并对其地下空间地质结构特征进行详细概述。结果表明,青岛市岩土体结构受基岩严格控制,影响着第四系沉积物的分布,其中岩体可划分为4类,第四系盖层可划分12层。基于数据构建的青岛市立体地质结构模型显示,下地壳的顶部埋深约12 km,上部地下空间开发的关键层范围为0~60 m,地表关键层的三维工程地质模型直观地展示其环境工程地质条件,便于提高对青岛市地质环境的整体认识,为后续地下空间开发建设提供科学依据。
It is urgent to develop the underground space efficiently and reasonably for the large-scale urban construction in Qingdao City,Shandong,China.The clear understanding of the geostructural characteristics of underground space in the city and providing a more scientific and reliable basis for rational planning and development of the urban underground space are important to meet the needs of urban sustainable development.Based on the data of urban geological survey and geoengineering investigation,this paper summarizes the regional structure,geomorphology,fractures,rock and soil structure and geoengineering conditions and introduces the geostructural characteristics of the underground space in detail for the city.Results show that the bedrocks strictly controlled the rock and soil structure and affects the distribution of quaternary sediments in Qingdao.The local rock masses can be divided into four types,and the Quaternary cap strata can be divided into 12 layers.The geo-structural model of Qingdao constructed by available data shows that the top buried depth of the middle-lower crust is about 12 km,and the key upper layer of the underground space development ranges from 0 to 60 m.The 3D geoengineering model of the key layer of the surface shows clearly the geoengineering structures,which is conducive to improving the overall understanding of the geological background of Qingdao and providing a scientific basis for the subsequent underground space development and construction.
