基于GIS的区域工程地质信息系统分析与设计——以山东省公路建设工程地质信息辅助决策系统研发为例

The Analysis and Programming of a Regional Engineering Geological Information System Based on GIS——Taking the example of the study and programming design of the assistant decision system of highway construction engineering geological information of Shan

以山东省公路建设工程地质信息辅助决策系统研发为例,分析了工程地质资料数据特点,基于MapGIS平台进行了工程地质信息系统的分析和程序设计。系统采用Access数据库设计实现了对钻孔与实验数据的管理,采用MapGIS图形库设计实现对图形资料的管理,采用叠加分析、DTM分析等空间分析技术结合已有研究基础实现公路选线科研阶段所需路基状况和土石方量等信息的自动分析。本文的研究为实现区域工程地质资料的信息化管理和应用提供了新思路。

Taking the example of the study and programming of the assistant decision system of highway construction engineering geological information of Shandong province, the characteristics of the engineering geological information were analyzed. The analysis of engineering geological information system and programming design based on MapGIS was introduced. By using Access database to manage the borehole and testing data, MapGIS graphic library to manage the graphic information, the system adopted such spatial analysis techniques as overlay analysis, DTM analysis etc. to realize automatic analysis of roadbed condition, earthwork volume and so on during the route selection stage. This paper presents a new method for realizing the informatization management and application of the regional engineering geological data.
