Temperature control, which is directly responsible for the project quality and progress, plays an important role in high arch dam construction. How to discover the rules from a large amount of temperature control information collected in order to guide the adjustment of temperature control measures to prevent cracks on site is the key scientific problem. In this paper, a mathematic logical model was built firstly by means of a coupling analysis of temperature control system decomposition and coordination for high arch dam. Then, an analysis method for temperature control information was presented based on data mining technology. Furthermore, the data warehouse of temperature control was designed, and the artificial neural network forecasting model for the highest temperature of concrete was also developed. Finally, these methods were applied to a practical project. The result showed that the efficiency and precision of temperature control was improved, and rationality and scientificity of management and decision-making were strengthened. All of these researches provided an advanced analysis method for temperature control in the high arch dam construction process.high arch dam construction, temperature control information, data mining, data warehouse, neural network model Citation:Zhong D H, Zhao C S, Ren B Y. Research on analysis method for temperature control information of high arch dam construction.High arch dams are generally located in mountainous regions or in gorges, with complex structure, long construction period, large amount of concrete pouring, high peak pouring intensity, and pouring without longitudinal joints, which leads to huge temperature rise of hydration heat inside the concrete in the process of construction. When the temperature difference reaches a certain level, the temperature stress, the main factor leading to dam cracks [1], comes about, which has a direct impact on the construction period and operation safety of the whole project. Therefore, it is the key point to make reasonable temperature control measures and to improve the monitoring and management of concrete temperature for ensuring quality and progress of high arch dam construction. Concrete temperature information at each control stage is collected and analyzed in order to get the whole picture of the temporal temperature and variation trend, to detect the weak link of temperature control timely, and to adjust temperature control measures dynamically. That is an effective method for getting a better temperature control effect and reducing or even eliminating the risk of cracks.Expanding the construction scale of arch dam requires a higher standard of temperature control. How to adopt scientific methods and advanced technologies to manage and analyze the massive data of temperature control so as to discover valuable information and assist construction management and decision-making timely and effectively has become an important content of temperature control research of high arch dam. Some achievements have been achieved. Zhong ...
