【摘要】：武汉市岩体结构和地质构造相对复杂,城市工程建设中获取的大量地质信息需要进行标准化并形成城市地质数据库进行管理,利用数据库中的各种数据开展了三维可视化建模研究工作,以便更好的服务于城市工程建设,本文研究内容主要包括:1、城市工程建设工作需通过资料收集、物化遥、钻探、测试等工作手段获取大量的地质信息,包括地质结构、水文地质参数、工程物理力学参数等,简单介绍了各项地质信息的获取途径,并针对武汉市地质填图单位划分不统一的现象,提出了武汉市地质填图单位划分规则。2、分析了数据管理系统的需求,选用MAPGIS-K9数据管理系统来建立城市地质数据库,对武汉市工程地质数据标准化和数据库建设内容进行了研究。3、研究了三维地质建模采用的数据模型——三维地质要素数据模型。针对城市三维地质建模的一般方法存在的问题,本文提出了适合复杂地质体建模的方法——分区交互式建模法。运用此法,对建模过程中遇到地层尖灭、断层、地层穿透等复杂地质现象提出了处理办法,对三维建模过程中的难点进行研究,对此本文提出了解决思路。4、选取了武汉市汉阳区和地铁2号线一期工程开展了三维地质建模工作,并对三种模型进行了可视化展示,同时利用MAPGIS-K9数据管理系统来对二维和三维地质数据进行分类管理,提出了地质数据分类管理的规则,建立了武汉市城市地质数据库,对我国城市地质数据库的管理有极大的意义,可指导城市工程建设及数据管理。
[Abstract]:The rock mass structure and geological structure in Wuhan are relatively complex. A large amount of geological information obtained in urban engineering construction needs to be standardized and the urban geological database should be formed for management. Using all kinds of data in the database to develop 3D visual modeling research work in order to better serve the urban engineering construction. The research content of this paper mainly includes: 1, the urban engineering construction work needs to be collected through the data collection. Physical and chemical remote, drilling, testing and other working means to obtain a large number of geological information, including geological structure, hydrogeological parameters, engineering physical and mechanical parameters, etc. Aiming at the phenomenon that the division of geological mapping units in Wuhan is not uniform, the rule of division of geological mapping units in Wuhan is put forward, and the requirement of data management system is analyzed. MAPGIS-K9 data management system is used to establish urban geological database, and the contents of standardization and database construction of engineering geological data in Wuhan are studied. This paper studies the data model of 3D geological modeling, the data model of 3D geological elements, and the problems existing in the general methods of 3D geological modeling in cities. In this paper, a new method for modeling complex geological bodies is presented, which is called the interactive modeling method. By using this method, the complex geological phenomena such as formation tip out, fault and stratum penetration are dealt with in the course of modeling. The difficulties in the process of 3D modeling are studied, and the solution. 4. The first phase of the project of Wuhan Hanyang District and Metro Line 2 is selected to carry out the 3D geological modeling work. At the same time, the MAPGIS-K9 data management system is used to classify and manage 2D and 3D geological data, and the rules of geological data classification management are put forward. The establishment of urban geological database in Wuhan is of great significance to the management of urban geological database in China, which can guide urban engineering construction and data management.
