摘　　要：地基工后沉降是评判地基处理效果的一个重要指标,针对分层总和法、计算机数值计算预测沉降存在的各种不合理假定,应用Origin软件对相当数量的实测沉降数据进行曲线拟合预测沉降体现了优势。通过指数模型、双曲线模型、Weibull模型的沉降预测值与实测值对比,双曲线模型有更高的预测精度,随着沉降监测向自动化发展,实测数据取得更加容易,为基于曲线拟合的沉降预测提供广阔的前景。Post-construction settlement of foundation is an important index to evaluate the effect of foundation treatment.In view of various unreasonable assumptions existing in layered summation method and computer numerical calculation to predict settlement,it is advantageous to apply Origin software to predict settlement by curve fitting a considerable number of measured settlement data.By comparing the settlement prediction values of exponential model,hyperbolic model and Weibull model with the measured values,the hyperbolic model has higher prediction accuracy.With the development trend of settlement monitoring towards automation,it is easier to obtain the measured data,which provides a broad prospect for settlement prediction based on curve fitting.
