| 摘 要： | 该文基于实测资料进行建筑物沉降预测。在灰色模型和泊松曲线模型理论的基础上,引入对非等间距数列进行变换处理的方法,从而建立了非等间距预测模型。结合建筑物沉降监测资料进行分析比较,结果表明,两种预测方法均能较好地反映建筑物的沉降趋势。

| Abstract: | Construction subsidence prediction is discussed based on observed data in this paper.According to the principle of Grey Model and Poisson curve,a transformation method for non-equidistant data sequent is introduced.Then,a prediction model is proposed.With observed data,the experiment result shows that both two predictive methods can reflect construction subsidence tendency well. |
