In order to rapidly and accurately predict the concrete pouring block＇s highest temperature during the construction of arch dam, based on uniform design, 30 sets sample data from concrete pouring block＇s 4 factors and 30 levels data of a construction concrete arch dam are chosen to do experiment. Selecting pouring temperature, cooling water flow rate, cooling water temperature and environment temperature as input vectors, the highest measured temperature as output vector, the highest temperature neural network intelligent prediction model of concrete pouring block is established. After training the neural network model, the highest temperature prediction model of concrete pouring block is obtained based on uniform design. Application results show that the model＇s prediction values agree well with the measured values and the operation speed is fast. It can rapidly and accurately predict the highest temperature of concrete pouring block of the construction site. Especially, it is suitable for construction organization to real time monitoring temperature change rule on the construction site.
