摘　　要：AR模型与α-β模型是建立变形测量动态预测模型的常用模型.文章介绍了这两种模型的建模方法,并用两个变形测量的实例对它们进行了比较.结果表明:两种模型的稳定性和预测能力基本相同,但α-β模型的建模方法更加简单方便.因此在建筑物的变形测量中,应优先考虑采用α-β模型建立变形预测模型.Both AR model and α-β model are usually used to establish dynamic forecasting model in deformation measurements. This paper introduces the modeling methods of both the models and compares them by means of two examples of deformation measurements. The result of comparison indicates that the stability and the forecasting ability of both models are almost the same, but the modeling methods of α-β model is simpler and easier than that of AR model. Therefore, α-β model should be the first to be used to establish deformation forecasting model in the deformation measurements of structure.
