【Abstract】 In this paper,finite element analysis software is applied to analyze the effect of pipe cooling in bridge pile cap construction.The effect of pipe cooling is demonstrated through the simulation and comparison of the three situations: there are cooling pipe and not,and the temperature of cooling pipe is lower.The record of the construction of a pile cap of a bridge in Shiyan City of Hubei Province that the simulation analysis in this paper is correct,and the conclusions offer the references for similar engineering.更多还原
