Real time thermal field analysis on Wudongde super high arch dam during construction

摘要

During concrete dam construction, concrete temperature monitoring and control is key to ensuring dam concrete quality and construction safety. In this study, a 2D thermal field restructuring method relating to the Kriging temperature interpolation is proposed. Based on dam site monitoring data of distributed optical fiber, the results indicated that the proposed restructuring method can be applied to effectively and quickly obtain 2D real thermal field. The evolution law of thermal field in early ages and temperature differences of concrete blocks based on the thermal field data are obtained. It also can be concluded that the proposed restructuring method could help obtain accurate and reliable restructuring monitoring data.
