摘　　要：变形监测工作对保障工程建筑物的安全有着重要作用,科学、准确、及时地分析和预报工程建筑物的变形状况,对工程建筑物的施工和后期运营尤为重要。灰色预测理论是一种运用较为广泛的预测分析方法,运用分段低次牛顿插值的方法对非等时间序列进行处理,并以某高层建筑物为例,分析非等间隔GM(1,1)模型在沉降预测中的精度与可行性,最终得出了有益结论。Deformation monitoring is important to the safety o^the construction of buildings. The deformation of the building is analyzed and predicted scientifically, accurately and in time. Grey forecasting theory is a widely used method of forecasting and analysis. Using the method of piecewise low order Newton interpolation to process the non-time series, and taking a high-rise building as an example, analyze the accuracy and feasibility of the non-equal interval GM （ 1, 1 ） model in settlement prediction.
