摘要
根据混凝土热传导方程,利用差分算法建立了混凝土内部与边界的差分格式,并利用Matlab的编程和可视化功能,对闸底板大体积混凝土浇筑21d的温度场进行了仿真计算。通过与实测值对比分析表明,该算法的计算精度可满足工程需要,且可将混凝土温度场分布进行可视化输出。
Based on the concrete heat conduction equation, the difference algorithm of interior and boundary is estab lished. The mass concrete of gate floor bottom＇s temperature field for pouring 21 days is simulated and calculated by u- sing the Matlab＇s programming and visual function. Through the comparative analysis with the actually measured value, the results show that its accuracy can meet engineering requirements and the temperature field distribution can be timely visual output.
