| Abstract: | This paper,based on a half-through concrete-filled steel tube arch bridge,calculated the hydration heat effect of mass concrete with the MIDAS finite element software.Through the analysis of the influence parameters of the main hydration heat effect,the optimal hydration heat construction control method is obtained.It effectively avoided the risk of hydration heat temperature control and concrete cracking during the construction of mass concrete,shortened the construction period and improved the economic benefit. |
