基于GIS的通用岩土工程勘察数据库系统的设计

Design of Universal Geotechnical Investigation Database System Based on GIS

通过对岩土工程勘察数据管理的需求分析,提出采用GIS技术和大型商用数据库管理技术开发通用的岩土工程勘察数据库系统。指出系统开发的关键是设计基于Geodatabase空间数据模型的空间数据库,实现空间数据和属性数据的一体化存储。通过对岩土工程勘察领域数据的分析,构建了系统的空间数据库模型,为数据库系统的建立提供保障,并指出了系统的功能模块与实现方案。另外,为了实现系统的通用性,设计了岩土工程勘察数据的要素分类编码方案。

To meet the demand for the management of the geotechnical investigation data,a plan is put forward to develop the database system by using GIS and commercial database management technology.That is pointed the most important part for this system is to design a geodatabase,which can implement the integrated storage of the spatial data and attribute data.By making a detailed analysis for the data of geotechnical investigation domain,a spatial dada model for the system is proposed to ensure the creation of the universal database system,then it has indicated the system＇s functional module and implement method.In addition,for the reason to realize the universality of the system,it has designed the data＇s classification and coding scheme.
