摘　　要：大体积混凝土重力坝采用大仓面浇筑,浇筑速度快,混凝土热传导性又差,在硬化过程中将产生温度应力.本文针对混凝土重力坝典型坝段,在给定施工进度条件下,进行施工期的温度场和徐变应力场仿真分析,对大坝浇筑块的温度和应力结果作出综合评价,计算结果可为溢流坝段的温控设计提供有益的参考依据.Mass concrete gravity dam is poured with large cabin,pouring speed,the thermal conductivity of concrete is poor,the hardening process will produce temperature stress. For typical dam sections in this paper,under the given condition of the construction progress,was analyzed through simulation analysis of temperature field and creep stress field during construction period,comprehensive evaluation of the temperature and stress results of the dam block was done,the calculation results can provide a useful reference for the temperature control design of the overflow dam section.
