摘要
为研究南洞庭湖特大桥塔座及首节塔柱大体积混凝土在浇筑过程中的温度应力水平,采用有限元仿真软件建立模型,分析现场浇筑情况下大体积混凝土温度及温度应力随龄期的变化情况,对比混凝土中有无设置冷却水管对大体积混凝土温控的重要影响。
To research the temperaturestress level in theconstruction of massconcrete of the South Dongting bridge pedestal and the first section of the tower, building model by using the finite element software and analyzing the changes in the temperature and temperaturestresswith curingtime, at the same time, to find the influence of cooling water pipes on the temperature control of large concrete
