| Abstract: | It was took the large-volume anti-radiation concrete in the radiotherapy department of a provincial hospital as the research object,the temperature gradient and change law were simulated through the finite element analysis software Midas Gen,it was used to simulate the impact of construction conditions and measures on project construction,optimize the plan and improve the suitability of the construction plan to the construction conditions,and reduce the occurrence of cracks in the concrete structure due to the excessive temperature gradient difference between the inside and outside.It could be used as a reference for the optimization of similar projects and temperature control measures. |
