Research on analysis method for temperature control information of high arch dam construction

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.
