摘要
ArcGIS作为常用GIS平台,多用于存储海量地理信息数据,将ArcGIS平台与相关岩土计算软件有机融合,是实现岩土工程实时分析功能的有效途径,但目前尚不能实现ArcGIS三维地层模型数据与岩土计算软件(如Geo-Slope)所需的输入数据间有效兼容。本文研究两个软件支持的文件格式类型及解析方式,提出了基于点集DXF文件和XML文件的地层数据转换与预处理方案。基于该方案开发数据转换与预处理程序,使三维地层模型向二维边坡模型的剖切、划分、数据整合与转化等操作流程自动化,初步实现从ArcGIS中导出能被Geo-Slope兼容的剖面数据文件并在过程中完成数据预处理,以取代人工耦合方式。以淮河淮北堤防工程为例,对数据转换与预处理方案进行分析,验证该技术与软件的实用性。
AreGIS is usually used in the storage of a large amount of geographic information data. Combining AreGIS platform with related geotechnical computing software is an effective way to take real- time analysis of geotechnical engineering. However, 3D strata data on ArcGIS platform cannot be used directly as the input data for geotechnical computing software such as Geo-Slope. This paper conducts a research on the data formats supported by both ArcGIS and Geo-Slope, and presents the detail procedures for data format conversion and data pre-analyzing based on DXF files and XML files. And an application for data conversion and pre-analyzing from 3D strata model to 2D slope section has been developed and it is more convenient for the process of strata sectioning, region dividing, and so on. The file exported by ArcGIS is then compatible with Geo-Slope. This paper presents an example of dike engineering in north Anhui Province, and the results has verified the practicability of the new method.
