Zusammenfassung: | A mass concrete construction temperature control method based on temperature rise regulation and control comprises the steps that a cement hydration and concrete heat transfer model based on an experiment is established; establishing a fine temperature field numerical calculation model based on the hydration degree according to structural geometric parameters, boundary heat exchange conditions and construction and maintenance measures; temperature control indexes of the highest temperature inside the model and the maximum temperature difference of the inner surface are extracted and compared with design requirements on the premise of meeting standard requirements; and the temperature meeting the requirements can be packaged and output as a temperature control technology. According to the method, a temperature rise curve is controlled on the basis of an inhibitor, so that a standardized hydration temperature rise and maintenance strategy is obtained, and meanwhile, the most appropriate pipe cooling layout sche |
