| 摘 要： | 本文以有限元软件ANSYS10.0为平台,通过生死单元的运用,模拟重力荷载按工程浇注程序分步作用情况,同时针对拱坝所受温度荷载的不同,依据稳态温度场分布和影响情况,把温度荷载作为耦合荷载的形式对拱坝进行应力分析。通过将模拟坝体施工浇注过程和体形优化设计有效的结合起来,得出了更加实际的拱坝体形。

| Abstract: | This paper takes finite element software ANSYS10.0 as a platform,through the use of cell life and death to simulate gravity load according to casting process step by step actions,while arch dam suffered for different temperature loads,based on steady-state temperature distribution and the effective situation,it analyses the stress of the arch dam taking the temperature load as coupled loads.The effective and realistic shape of arch dams is obtained combining with the simulation of the shape optimization design and dam construction. |
