基于关联规则挖掘的混凝土坝温控方案优化
Optimization of the temperature control scheme of concrete dams based on association rule mining approach
摘要
Abstract
[Objective]The Feedback Design(FD)of temperature control measures during the construction period of a concrete dam require that the individual temperature control measures for each planned dam block for pouring should be proposed in a short period of time to ensure the timeliness of the on-site construction guidance.However,the parameter adjustment steps in the FD process mainly rely on the personnel,professional knowledge,and engineering experience of the computing staff,which is not conducive to improving the FD efficiency.[Methods]In this study,association rule mining theory is applied to reveal the influence degree of common temperature control measures for the temperature control effect of a concrete dam.An associa-tion rules mining model for the temperature control data is established based on the Xiluodu high arch dam project.The associ-ation rules between the temperature control parameters and the temperature control index of the dam in the initial cooling stage and the temperature-dropping period of the middle cooling stage are mined,and the quantitative relationships are obtained.[Results]The results show that in the temperature control period of the initial cooling stage:(1)the concrete pouring tempera-ture needs to be controlled between 11～12℃,(2)the average inlet water temperature needs to be controlled between 7.5～9.5 ℃,and(3)the average water flow needs to be controlled between 27～35 L/min.Additionally,in the temperature drop-ping periods of both the initial cooling stage and the middle cooling stage,the average inlet water temperature needs to be con-trolled between 14～16 ℃ and average water flow needs to be controlled between 16～22 L/min.[Conclusion]The discovered knowledge indicates relationships between the temperature control indexes and temperature control measures in pouring blocks for the Xiluodu high arch dam that enable the engineers to make reasonable decisions,which provides a reference for the scien-tific and efficient adjustment of the temperature control measures and makes some contributions during the construction period of the Xiluodu high arch dam.关键词
