摘要
首先简要回顾国内外工程师，在碾压混凝土坝温度徐变应力研究方面，所作的一部分工作，分析这些工作的理论基础和计算方法。然后介绍国内几家单位，在仿真分析方面的进展。最后对其中仍面临的困难，如材料参数描述上的困难、施工参数描述上的困难、计算规模与计算效率上的困难、本构模型描述上的困难、结构边界可视化处理上的困难等进行了讨论。
Achievements in the field of thermal creep stress analysis for RCC dam were reviewed briefly. Also, the methods and the basis used by the scientists were introduced. Then the improvements of simulating the whole construction process were illustrat- ed. Some problems in face of simulating the thermal creep stress fields were discussed and listed in the following. How de- scribe the material and construction parameter? How decrease the scale of computational model or enhance the computational efficiency? How deal with the constitutive law of concrete? How make the visualization of structural boundaries ?
