ByH.B. Zhang, C.L. Lv, M. Ma, S.B. Chai & X. Ren

Combined with the actual construction environment parameters, the model calculation results are compared with the data obtained by the analysis of hydration heat characteristics of box beam concrete. However, it is difficult to obtain the authentic change law of temperature field with time and space due to the complexity of temperature field and the difference of construction environment. In this paper, a zero concrete block is constructed using long-span continuous rigid frame railway bridge as the engineering background and testing and analyzing the change of temperature field of hydration heat and stress field distribution of zero concrete block poured.
