摘要
在现有基于数据库技术的大坝安全监测系统研究的基础上,结合工程项目的具体情况以及大坝监测数据分析的特点,设计及构建了大坝安全监测数据仓库系统,为监测资料的分析查询、信息挖掘和综合评判提供了良好的数据环境.利用联机分析处理(OLAP)与数据挖掘(DM)技术对监测数据仓库中的数据进行了分析和挖掘,使安全监控资料的作用得到了进一步的发挥,为安全监控评判和决策的深化提供新的途径.
In combination with the reality and monitoring data of dam projects, a data warehouse (DW) for dam safety monitoring was designed and constructed, providing a good environment for monitoring data analysis and query, data mining (DM) and comprehensive evaluation. By use of the on-line analytical processing (OLAP) tool and DM technology, dam monitoring data in data warehouse were analyzed and mined, and the function of the monitoring data was further utilized. The study provides a new approach for evaluation of result of safety monitoring and decision making for dam projects.
