Zusammenfassung:The invention relates to a method for controlling a mass concrete cooling introduced water flow. The method comprises the following steps of: (1), obtaining a value of a historical concrete introduced water cooling efficiency; and (2), calculating a required next flow control value according to the value of the historical concrete introduced water cooling efficiency and a cooling amplitude and a cooling time interval to be required in the future, and uniformly decreasing concrete temperature according to design requirements through the above steps. According to the method for controlling the mass concrete cooling introduced water flow, provided by the invention, by introducing dynamic adjustment of a practical cooling flow coefficient alpha and by matching with auxiliary modification of a lag coefficient ksi, internal temperature of concrete can be uniformly and stably decreased, and the purpose of controlling a target temperature can be achieved during an expected time; furthermore, automatic calculation of
