Abstract:

In response to the common pain points of temperature cracks and uneven pouring quality in the concrete construction of high arch dams in Anhui Province, this article conducts a special study on intelligent temperature control and refined construction technology for warehouse surfaces. By deploying sensor networks to achieve real-time monitoring of temperature fields, a temperature strength stress coupling numerical model is established, and a temperature control prediction system based on big data analysis is built. Finally, a refined construction technology system is proposed that integrates precise proportioning optimization, special treatment of interlayer bonding surfaces, intelligent maintenance, and other full links. Engineering practice verification shows that this technology system can improve temperature control accuracy by 30%, reduce the proportion of temperature cracks by more than 40%, and increase construction efficiency by 25% and shorten the total construction period by 15%. It provides effective technical reference and practical guidance for the construction of high arch dam projects under similar climatic conditions.
