摘要
考虑冷却水管的作用,采用有限元法建立大体积混凝土桥墩水化热温度场的精确计算模型,应用分析软件AN SY S对高墩刚构桥的墩身混凝土水化热温度场进行数值分析,通过现场温度实测结果与计算值的比较,表明本文的分析方法精度较高.
Considering the effects of water pipe cooling, an accurately calculating model for the hydrated heat temperature field of massive volume concrete piers was established in this paper. And using this model and the analytical software ANSYS, a numerical analysis was conducted of the hydrated heat temperature field of the body concrete of a high-pier, rigid-frame bridge. By a comparison of the calculated results and field observation results of the temperatures, the present method of analysis was proved to be of high precision.
