| Abstract: | With the theory of three-dimensional transient state temperature fields,a finite element model for calculating temperature fields of mass concrete is created.The laws of distribution and time-dependent variations of the temperature fields inside the pile caps are investigated.And a set of complete temperatures and crack control plans has been drawn up,the effect of which proved to be good in practice. |
