为解决筏板基础大体积混凝土由于水化热产生的温度裂缝问题,在罗马假日商住小区筏板基础大体积混凝土施工温度监测基础上,采用有限元软件ADINA对筏板基础进行温度场模拟仿真分析,研究了模型各断面的温度变化曲线及温度场随时间变化规律.结果表明:采用有限元软件ADINA对筏板基础进行温度场模拟,其结果与测温数据基本吻合,说明采用数值模拟的方法,可以有效的预测大体积混凝土结构的温度变化趋势.
In order to solve the temperature crack problem of raft foundation mass concrete due to hydration heat, the finite element software ADINA was used to simulate the temperature field of raft foundation on the basis of monitoring the temperature of raft foundation mass concrete construction in Roman holiday commercial and residential area. The results show that the temperature field of the raft foundation is simulated by finite element software ADINA, and the result is in good agreement with the temperature measurement data, which shows that the numerical simulation Method, can effectively predict the temperature trend of mass concrete structures.
