摘　　要：对同一工程实体的沉降而言,通常可采用多种数学模型进行拟合、预测。但找一种建模简单且能够有效反映沉降变形规律的数学模型往往是困难的。文中介绍常用的7种数学模型的基本理论,并对模型在沉降预测中的适用情况和优缺点进行比较分析;结合工程实例,运用Matlab对7种数学模型进行验证并给出结论。In terms of the settlement of the same engineering entity, it usually uses a variety of mathematical models for fitting and predicting, which is often difficult to find a simple modeling with effective reaction of the settlement deformation law. On the basis of the relevant theories, seven basic mathematical models are introduced completc with the advantages and disadvantages in settlement prediction. Finally with engineering examples, Matlab is used to verify the seven mathematical models and the conclusion is given.
