本文研究了如何用谱分析方法进行建筑物原型观测资料的分析处理，对应用中所面临的困难采取了三种不同的方法加以处理。通过补偿模型来提取定量分析（如统计模型）建模后残差部分中的有规律成份即补偿项，加到原模型中来提高预报精度和结构性态评价的准确性。通过实例计算证明了补偿模型的合理性和可行性。
This paper studies how to use spectrum analysis method to analyze and process the building prototype observation data and adopts three different methods to deal with the difficulties in the application. The compensation model is used to extract the regular components in the residual part of the quantitative analysis (such as the statistical model), that is, the compensation term, and add it to the original model to improve the prediction accuracy and the accuracy of the structural state evaluation. The case study shows that the compensation model is reasonable and feasible.
