The change of temperature in the dam is big, and except for the dam crest is free, the other three surfaces are restraint by base rock, and so, the big thermal stress in arch dam probably occurs.

除了坝顶为自由边界外，其他三面都受到基岩的约束，温度变形受到的约束比较大，因此在坝体内出现较大的温度应力。

Thermal load in arch dam is only inferior to water pressure in arch-dam design. At the boundary of the upstream reservoir, the rationality and precision of water temperature analysis is very important to consider the deformational behavior of dams.

拱坝的温度荷载是拱坝设计中仅次于水压荷载的的主要基本荷载，上游边界库水温度场分析的合理性、准确性对反映坝体受力性态尤为重要。

Findings show that, for be in the wrong frozen soil wrought in favor of thermal disturbance, insulating layer thickness respond adopt dam insulating pipe hull skin temperature' calculation procedure.

研究结果表明，为不对冻土造成较大热扰动，保温层厚度应采用控制保温管外表面温度的计算方法。

Therefore the construction process and material properties of RCC arch dam must be simulated precisely so as to take reasonable engineering measures to reduce the thermal stress in the dam.

所以，必须准确模拟碾压混凝土拱坝的施工过程和材料特性，仿真计算拱坝温度场和应力场，以便采取合理的工程措施，减少坝体的温度应力。
