【摘要】：论文搜集了长春市中心区大量基础地质资料，其中包括一千多个钻孔资料。论文分析研究了长春市中心区的工程地质分布特征，将长春市中心区按照其地貌特征划分为两个大的工程地质地貌单元，并对其地层层序进行了划分。论文从地质环境、人口经济、气候环境、城市经济建设发展现状等几个方面论述了长春市目前大规模开发利用地下空间的适宜性。论文分析了长春市现有的岩土工程勘察资料的主要存储数据格式，利用CASE工具Power Designer构建了长春市中心区工程地质数据仓库的物理模型，并在Microsoft SQL Server2005中实现了数据仓库的物理存储，，从而能够将勘察单位资料库现存的大量勘察数据快速读取并存储入长春市中心区工程地质数据仓库中，用于进行与地下空间开发利用主题相关的研究与分析。论文利用GOCAD软件分别模拟了线状工程和面状工程的三维可视化工程地质地层模型。对按照宏观地层层序的划分，对钻孔数据的地层缺失及透镜体夹层情况进行了调整，在此基础上建立了长春市中心区三维工程地质地层模型和属性模型，通过对模型的研究分析进一步摸清了长春市中心区的工程地质地层分布的特点。论文探讨了目前长春市地下空间开发利用的工程类型及其分布深度，分别从地表以下0~3m浅层区域、3~15m中层区域、15~30m深层区域三个层次探讨了影响工程开发利用的工程地质因素。借助粗糙集理论对部分影响要素进行了约简，利用模糊层次分析法计算了约简后的影响要素的权重值，利用可拓学理论分别对不同深度区域的工程建设适宜性进行了评价，并利用其评价结果分别对浅层、中层和深层区域的岩土体可利用性进行了可拓综合评价。论文应用长春市地下空间岩土体可利用性综合评价结果对长春市地铁一号线的线路周边区域进行了分析评价。论文的研究结果具有实用价值，能够为长春市地下空间规划和工程建设提供参考依据。
[Abstract]:This paper collects a large number of basic geological data, including more than 1000 boreholes in the central area of Changchun. This paper analyzes and studies the engineering geological distribution characteristics of the central area of Changchun, divides the central area of Changchun into two large engineering geological and geomorphological units according to its geomorphological characteristics, and divides its stratigraphic sequence into two parts. This paper discusses the suitability of large-scale exploitation and utilization of underground space in Changchun from the aspects of geological environment, population economy, climate environment and present situation of urban economic construction and development. This paper analyzes the main storage data format of the existing geotechnical engineering survey data in Changchun, and constructs the physical model of engineering geological data warehouse in the central area of Changchun by using CASE tool Power Designer. The physical storage of the data warehouse is realized in Microsoft SQL Server2005, which can quickly read and store a large number of survey data from the database of survey units into the engineering geological data warehouse in the central area of Changchun City. Used for research and analysis related to the subject of underground space development and utilization. In this paper, the 3D visualization engineering geological stratigraphic models of linear engineering and plane engineering are simulated by GOCAD software. According to the division of macroscopic stratigraphic sequence, the stratigraphic missing of borehole data and the intercalation of lens body are adjusted. On this basis, the 3D engineering geological stratigraphic model and attribute model in the central area of Changchun are established. Through the study and analysis of the model, the characteristics of engineering geological stratigraphic distribution in the central area of Changchun are further investigated. This paper discusses the engineering types and distribution depth of underground space exploitation and utilization in Changchun, and discusses the engineering geological factors that affect the engineering development and utilization from three levels, namely, 0 ~ 3 m shallow area below the surface of the earth's surface, 3 ~ 15 m middle layer area and 15 ~ 30 m deep layer area. By means of rough set theory, some influencing factors are reduced, the weight of the reduced factors is calculated by using fuzzy analytic hierarchy process, and the suitability of engineering construction in different depth regions is evaluated by extension theory. The extensibility of rock and soil in shallow, middle and deep layer is evaluated by using the evaluation results. In this paper, the comprehensive evaluation results of the availability of rock and soil mass in underground space of Changchun City are applied to analyze and evaluate the surrounding area of Line 1 of Changchun Metro. The results of this paper are of practical value and can provide reference for planning and engineering construction of underground space in Changchun.
