摘要
采用MIDASCivil有限元软件进行建模分析,研究水化热温度峰值发生的时间,内部温度应力的变化情况,并在混凝土浇筑前采取了针对性的管冷降温措施,通过软件建模分析的方式有效控制了由于混凝土的过快升温导致的结构裂缝病害,为类似的工程施工提供借鉴参考。
This paper using the MIDAS Civil finite element software modeling analyses the hydration heat temperature peak time,the changes of internal temperature stress in the concrete pouring, and cooling pipe before casting concrete.This project effectively controlled the structural crack caused by concrete heat up to fast by means of software modeling analysis,providing reference to similar project.
