摘　　要：本文利用牛顿插值法将非等时距建筑物沉降监测数据插值生成等时距拟合数据,结合灰色理论建立了非等时距的沉降预测模型,并用C#语言对该模型进行了编程实现,最后以实际的某建筑物沉降监测数据为例,对该模型进行了检验,表明该模型具有很高的精度和灵活性,能够直接应用于工程实践,具有很高的实用价值。In this paper, the subsidence forecasting model of non-isometric time sequence is established, through that non-isochronous data from building subsidence monitoring can be interpolated to generate isochronous fitting data based on Newton＇ s interpolation method. And it is achieved with C# programming language. Finally the model has been tested by the real case of building subsidence-monitoring data, which indicates that this model has high accuracy and flexibility. It should be very benefit andcan be directly applied to engineering practice.
