摘　　要：位移温度分量是混凝土坝位移的主要位移分量之一,其计算较为复杂,本文简述混凝土重力坝位移确定性模型中计算温度分量的不同方法和适用条件,重点论述用“单位边界温度”模型或“单位气揾”模型计算温度分量的基本原理、方法和步骤,并列举应用实例,实践证明,该法计算简单、适用性强、精度可满足要求,是值得推广和进一步探索研究的方法。The displacement component of temperature is one of the main displacement component in concrete dams and its calculation is complex. In this paper, the authors analyze its different calculation methods and application conditions. Emphasis is laid on the analysis of basic pririciple, calculation methods and procedure using 'unit boundary temperature' model and 'unit air temperature' model for calculating displacement component of temperature. Some examples of application in actual engineering are given. It is proved that the method is simple, applicable and accurate. It is worth to spread and study further.
