NSYS模拟大体积混凝土浇筑过程的温度场分析

fter the completion of casting the mass concrete, lots of hydration heat produces during cement hardening. Because the internal heat loss is not so fast as that on the surface, the differences of temperature are excessive between interior and exterior. What's more, these excessive temperature differences will produce temperature stress and temperature deformation. The temperature stress is the main reason that caused the mass concrete cracks. This paper took a high-rise building in Xiangfan for example, with the ANSYS finite element analysis software, mainly through simulating the distribution of temperature field and stress field, and comparing the calculated results with the actual situation, we can see the results of the analysis are broadly consistent with actual situation. However, some differences still exist, which are related to calculation model parameters and the treatment of boundary conditions.
