摘 要: 采用有限元软件ABAQUS对某一水闸加固工程中新浇筑底板的非稳定温度场与徐变温度应力进行计算,分析过程中采用ABAQUS提供的用户子程序DFLUX和UMAT. 将计算结果与现场实测的温度场和温度应力的结果进行了比较,结果表明:ABAQUS计算结果的精度较为理想,可以在混凝土温度场和温度应力等问题的计算中使用该软件。
关 键 词: 固体力学;温度场;徐变温度应力;二次开发;有限元

Abstract: In this paper, ABAQUS is used to compute unsteady temperature field and creep thermal stress of a new water board of some floodgate reinforcement project. User subroutine DFLUX and UMAT are also used in the analysis. Compared with the measured data of temperature field and thermal stress in the reinforcement project, the computation results indicate that ABAQUS is feasible in computation of temperature field and creep thermal stress of concrete.
Key words: solid mechanics; temperature field; creep thermal stress; redevelopment; finite element
