摘　　要：本文结合董家村渡槽施工期工程项目,利用ANSYS有限元软件建立了渡槽施工期仿真计算模型,对埋设在大体积混凝土中的冷却水管的温度场进行计算,并分析水管的布置方式、直径、通水流量、水流速度及冷却水温等因素对温度场的影响。结果显示,在渡槽施工期选择合理的冷却水管布置方案,可以有效降低混凝土中的温度,从而达到防止混凝土产生裂缝的目的。In this paper,combined with the Dongjiacun aqueduct construction project,the simulation calculation model of aque⁃duct construction period is established by using ANSYS finite element software,and the temperature field of the cooling water pipe buried in the mass concrete is calculated,and the influence of the water pipe layout,diameter,water flow,water flow speed and cooling water temperature on the temperature field is analyzed.The results show that the temperature in concrete can be reduced effectively by selecting a reasonable arrangement of cooling water pipe during the construction period of aqueduct,so as to prevent cracks in concrete.
