摘要
采用温度应力计算理论,以天津滨海新区响螺湾某工程为例,选取1/4底板计算模型,采用ANSYS软件进行有限元分析,分析了底板混凝土12天的温度场分布和变化规律。将有限元计算结果与现场实测数据作对比,计算结果表明,有限元仿真计算可以有效的模拟施工期温度场随龄期的变化,为采取温度控制措施防止温度裂缝提供计算分析数据。
1/4 concrete floor of a project of Xiangluowan in Tianjin Binhai New Area was selected and analyzed using ANSYS finite element software.The temperature field distribution and mutative disciplines in 12 days of slab concrete were researched.The results of the finite element analysis were compared with the measured data to find that finite element simulation calculation can simulate the temperature field changes with age effectively and provide reference for taking temperature-controlling measures to prevent temperature cracks.
