摘　　要：根据热传导理论与粘弹性理论采用平面与空间有限单元法,按照砼坝的施工浇筑、蓄水与正常运行过程,考虑随时间变化的各种因素(包括结构的、材料的与环境的)进行动态的增量的全过程仿真计算,得出大坝在全过程中的温度与应力变化情况。Based on theories of heat transfer and viscoelasticity and allowing for many factors (such as the construction, storage and normal operation, structural materials and enviroment), the authors of this paper made the dynamic incremental calculations of the whole course emulation by two and three-dimensional finite element methods, They obtained the values of the variation in temperature and stress of the dam. The useful results can be used in the designing, construction and operation of concrete dams.
