The finite element analysis of composite foundation raft temperature field

Through the finite element software of abaqus to analyze composite foundation raft of the concrete placement temperature field. Compared the analysis results by the simulate results and the actual results. The analysis results indicate that the finite element model have been established by can simulate the actual concrete temperature field very well. The analysis results show that for the small thickness raft should be controlled the outside temperature effectively, in order to reduce the raft influence by temperature.
