Three kinds of joint elements for finite element analysis of temperature field are given, ie, the joint element with finite thickness, the joint element with nearly zero thickness and the simplified joint element.

• 摘要目前混凝土坝的仿真分析正从单坝段仿真向全坝仿真发展，因而需要采用接缝单元，笔者给出三种温度场接缝单元的计算模型：有限厚度接缝单元、近零厚度接缝单元及简化接缝单元。
