摘要
为了高拱坝的安全施工和运行采用有限元法模拟了锦屏一级工程混凝土拱坝的整体施工过程和30 a运行过程,结果揭示了300 m级高拱坝的温度历时变化过程、坝体准稳定温度场及应力场分布规律,对设计和施工具有重要的参考价值。
For the safe construction and operation of high arch dam, the concrete arch dam construction and operation procedure during 30 years in Jinping-1 engineering is simulated by finite element method. The results show the temperature duration,the distribution patterns of quasi steady temperature field and stress field of 300m grade high arch dam. Important reference is provided to designing and construction in the aspect of temperature control and cracking prevention.
