摘要
针对分期施工的碾压混凝土重力坝的施工和结构特点，对其应力计算和稳定分析的有限元方法进行了讨论，并结合了程实例计算分析，对前后期新老混凝土温度效应对坝体应力的影响、坝体的渐进破坏过程和可能失稳方式以及真实安全度表达进行了初步探讨．
The FEM of stress computation and stability analysis on roller compacted concrete dam constructed by stages is discussed in accordance with the characteristics of its construction and structure. An investigation into the effect of the temperature difference between two stages concrete on the stress of a dam body, the dam failure process and mechanism, and the expression of the real safety is made with a project instance.
