摘要
以经典的热传导方程为理论基础,采用大型有限元程序ANSYS的热-结构耦合分析方法,对某大坝的温度场和应力场进行了模拟分析和计算,得到了大坝内的最高温度和主应力的分布,为在设计和施工过程中采取有效的防裂措施提供了指导。
Based on the classical heat conduction fomula＇s theory,using massive finite element program ANSYS of the heat-structure accouplement analysis method,the paper carried out the simulating analysis and calculation for the dam＇s temperature and stress field and finally obtained the max temperature and main stress＇ distribution in dam.It can provide the effective guides for anti-break measures during designing and constructing.
