拱坝施工期温度场及温度应力仿真计算

摘要

With three-dimensional finite element method,the temperature field and thermal stress of the arch dam of a hydropower station on Yunnan Province during construction period were carried out simulation analysis,it got the general rules of the dam temperature field and thermal stress distribution and provided a valuable reference for the concrete arch dam temperature control measures design.%采用三维有限元法对云南省某水电站老坝线的拱坝坝体施工期温度场及温度应力进行仿真分析,得到了拱坝温度场及温度应力分布的一般规律,为混凝土拱坝的温控措施的设计提供有价值的参考依据。
