| Abstract: | Based on research and practice of Sutong Bridge south pylon pile cap temperature control on massive concrete,this paper performs simulation on temperature field and stress field for pile cap by means of Finite Program.Calculation result is used to work out temperature control criteria, put forward reasonable temperature control measures and carry out monitoring on site.Through comparison and analysis of measurement data, correctness of theoretical calculation and temperature control measures is verified, so as to provide successful experiences to be followed in similar projects in the future. |
