【摘要】：进入21世纪，世界各地城市生存环境、城市人口和城市地域规模都趋近于饱和，人口众多、交通拥堵是城市的通病，严重制约着城市的可持续发展。进行城市地下空间开发，节约有限的土地资源，这是解决城市化过密,地面交通拥堵等问题的有效途径。地下空间具有环境条件相对稳定、施工条件不受气候条件限制等诸多优点。在现代城市建设过程中，充分发挥地下空间的环境优点，与地上空间工程建设互相结合、互相补充,这样就能创造一个比较适宜人类居住的城市生存空间。因此,近年来城市地下空间的开发和利用成了未来城市发展空间的重要方向。开发利用地下空间可以扩展新的使用空间，在一定程度上缓解现代城市发展的生产及生活用地矛盾、交通拥阻等问题。地下空间开发涉及空间资源合理规划、地质风险控制、工程施工技术、建筑成本等诸多因素，地下空间工程建设施工工期长、技术难度大、建设成本高。因此，进行城市地下空间开发及利用适宜性评价，是现代地下工程研究领域一个重要课题，，对未来城市建设的发展方向，具有十分重要的实际意义和指导意义。本论文第一部分介绍了城市地下空间开发的重要意义和国内外在地下工程建设方面的研究现状；第二部分介绍了石家庄城市地质概况和地下空间开发利用存在的主要问题；第三部分以大量的地质资料为基础，把影响城市地下空间开发利用的因素分成工程地质条件、水文地质条件、岩土体条件、地面及地域位置条件和不良地质条件五个方面；第四部分运用层次分析法，确定了影响地下空间开发的地形地貌、地层结构、地层稳定性、地下水深度等十四个评价指标的权重，将各个评价指标数值化，然后根据灰色数学理论计算出评价指标数列与各评价指标界限值数列之间的关联度，确定适宜性等级，以GIS底图为基础，利用综合叠加的方法得出了石家庄地下空间开发及利用适宜性分区图；最后做出总结，为石家庄地下空间开发的规划、开发、设计、施工等提出建议。
[Abstract]:In the 21st century, the living environment of cities around the world, urban population and urban area scale are approaching saturation, population is large, traffic congestion is a common problem of cities, which seriously restricts the sustainable development of cities. The development of urban underground space and the saving of limited land resources are effective ways to solve the problems of urbanization and traffic congestion. Underground space has many advantages, such as relatively stable environmental conditions, construction conditions are not restricted by climatic conditions and so on. In the process of modern city construction, the environmental advantages of underground space should be brought into full play, and the above ground space construction should be combined with each other, thus creating a city living space suitable for human being. Therefore, in recent years, the development and utilization of urban underground space has become an important direction of future urban development space. The development and utilization of underground space can expand the new use space, alleviate the contradiction of production and living land, traffic obstruction and so on in the development of modern city to a certain extent. The development of underground space involves many factors, such as reasonable planning of space resources, geological risk control, engineering construction technology, construction cost and so on. The construction period of underground space engineering is long, the technical difficulty is great, and the construction cost is high. Therefore, it is an important subject in the field of modern underground engineering to evaluate the suitability of the development and utilization of urban underground space. The first part of this paper introduces the significance of urban underground space development and the domestic and foreign research status in underground engineering construction; The second part introduces the geological situation of Shijiazhuang city and the main problems existing in the development and utilization of underground space, the third part divides the factors affecting the development and utilization of urban underground space into engineering geological conditions based on a large amount of geological data. Hydrogeological conditions, rock and soil conditions, ground and regional location conditions and poor geological conditions. Part four uses the Analytic hierarchy process to determine the topography, geomorphology, stratigraphic structure, stratigraphic stability that affect the development of underground space, The weight of 14 evaluation indexes, such as groundwater depth, is numerically valued, and then the correlation degree between the evaluation index series and the limit value series of each evaluation index is calculated according to the grey mathematics theory, and the suitability grade is determined. Based on the background map of GIS, the paper obtains the zoning map of the development and suitability of underground space in Shijiazhuang by using the method of comprehensive superposition, and finally makes a summary, and puts forward some suggestions for the planning, development, design and construction of underground space development in Shijiazhuang.
