【摘要】 本文根据热传导理论与粘弹性理论，采用空间有限单元法，按照大坝混凝土浇筑、蓄水与正常运行过程，考虑随时间变化的各种因素（结构的、材料的和环境的），进行增量的全过程仿真动态分析，得出大坝在全过程中的温度与应力变化情况，供大坝施工设计、结构设计和运行管理应用．更多还原

【Abstract】 Based on the theories of heat transfer and visco-elasticity,by using finite element method, the temperature and stress variations of concrete arch dam in the processes of construction, impounding and operation are being investigated according to the dynamic increment emulation.This method is pratical for design,construction and management.更多还原
