The measures and equipments for temperature control in pouring concrete for Three Gorges Project Ⅱ stage construction are introduced and various factors affecting the pouring temperature are analysed in the paper.BP models of artificial neural networks learnt and trained by trial test studies with 89 set of data obtained from field observation are used to predicate the final temperature of concrete during the construction of TGP.The results through two sets verification show that artificial neural networks have a good application potential in the studyfield of temperature control for monolithical concrete.
