青藏铁路路基病害决策支持系统数据库分析

通过对青藏铁路可能产生的路基病害的分析 ,笔者提出了建立青藏铁路路基病害数据库的重要性 ,给出了数据库的项目设计 ,研究了各种数据集的处理方案、数据工作空间和数据逻辑分组 ,并且采用数据仓库和面向对象的数据设计方式对数据库进行集成设计 ,给出了青藏铁路信息系统数据仓库体系结构以及数据在病害系统中的流程 ,建立了较完整的路基病害数据库内容。该研究为病害整治系统的进一步开发奠定了基础 ,可为将来青藏铁路可能产生的路基病害的迅速整治、降低铁路运营后的维护费用提供技术支持。

Study on Database for Decision Supporting System of Embankment Disasters on Qinghai-Tibet Railway

By analyzing the threat of the embankment disaster on Qinghai-Tibet railway, the importance of the disaster database is emphasized; and the project design of database is provided. Schemes of data collection, work space of the data and logical grouping of the data are studied. At the same time, the system structure of database for information system of Qinghai-Tibet railway using OOD design is given to establish the content of the database. This database makes the foundation for further development of the system. It would also provide support for instant repair of permafrost embankment and lowering the maintenance cost.
