摘要
针对溪洛渡大坝施工期大量的温度监测数据难以集成和访问的问题,基于数据仓库相关理论和设计方法,构建了溪洛渡大坝温度监测数据仓库,在已建成数据仓库的基础上,以冷却水温与最高温度两个指标量之间的关联关系为目标,采用关联分析方法对温度数据进行深度挖掘。结果表明,在溪洛渡大坝施工过程中要严格控制冷却通水温度不超过15℃,以防止最高温度超过上限影响大坝安全。
In consideration of the limitations that amount of temperature monitoring data was difficult to integrate and access in the construction of Xiluodu Dam,temperature monitoring data warehouse was constructed based on the related theory and design method of the data warehouse.With the incidence relation for the goal between two indicators of cooling water temperature and maximum temperature,temperature data was mined deeply by adopting the method of correlation analysis based on the constructed data warehouse.The result shows that cooling water temperature should be strictly controlled no more than 15 ℃to prevent the highest temperature exceed the upper limit which will affect the safety of the dam.
