大体积混凝土的广泛使用,以及混凝土结构中温度裂缝的产生,使工程技术人员越来越关注早期混凝土热学和力学性质,以便能够进一步预测混凝土结构的温度场、应力场和温度裂缝。大体积混凝土分层浇筑过程中温度场的仿真分析有一定的技术难度和复杂性,而利用有限元程序ANSYS通用平台,讨论模拟混凝土温度场理论上的可行性,为研究仿真计算提供了依据。
The widespread use of mass concrete and the generation of temperature cracks in concrete structures have led engineers and technicians to pay more and more attention to the early thermal and mechanical properties of concrete in order to be able to further predict the temperature field, stress field and temperature cracks of the concrete structure. The simulation analysis of the temperature field in the process of layered pouring of mass concrete has certain technical difficulties and complexity. Using the finite element program ANSYS universal platform, the theoretical feasibility of the simulated temperature field of the concrete is discussed, which provides a basis for the study of simulation calculation.
