摘　　要：本文以某特大悬索桥的索塔承台为例,利用ANSYS有限元分析软件,在模拟其分层浇筑过程的基础上,分析了承台在水管冷却作用下的温度场分布,从而得出水管的降温效果。其中,本文重点分析了冷却水管间距、开始通水时间、管材对冷却效果的影响。Taking a concrete pile cap of a large suspension bridge as an example and based on simulating the layered pouring process of the pile cap, this paper analyzed the temperature field under the cold water cooling condition and reached conclusions about the cooling effect of water pipes using software ANSYS. In the analysis, the influences of pipe spacing, starting time cooling effect are made as focal points. of watering and pipe material on the water pipe＇s

关 键 词：大体积混凝土 温度场 水管间距开始通水时间 管材
