摘　　要：通过分析建筑物沉降变形规律,并参考相关文献,提出一种基于二次平滑和指数曲线的串联式组合预测模型,核心思想是汇集两种方法的优点,对变形数据进行处理,以期能够最大限度地提高拟合、预测精度。文中就基础理论和建模流程进行详细介绍,并以工程实例加以验证,结果表明,组合方法建模简单,计算结果有效、可靠。By analyzing the deformation pattern of building settlement, on the basis of relevant literature, it proposes a combined forecasting model based on secondary smoothing and index curve, of which the core idea is to bring together the advantages of both methods for deformation data processing, in order to maximize the fitting and prediction accuracy. Its basic theory and modeling process are described in details and verified with engineering examples. The conclusion shows that the combination of modeling method is simple, and the results are valid and reliable.
