| 摘 要： | 介绍了Logistic增长曲线模型,通过实测数据建立沉降预测模型,拟合出s-t曲线,用平均绝对百分误差(MAPE)来评价预测模型拟合的精度,发现Logistic模型属于高精度拟合.将预测数据与实际观测数据进行对比分析,预测精度较高.结果表明该模型可用于高层建筑物的沉降预测情况.

| Abstract: | This paper introduces the curve model of Logistic growth,and through the measured data,builds the prediction model of subsidence,fits out s-t curve,with mean absolute percent error(100 % MAPE) to evaluate the fitting precision of the prediction model,that Logistic model belongs to high fitting precision were found.Compare and analyze the forecast data with actual observation data to show the high forecasting accuracy.The result shows that the model can be used in the prediction of high-rise buildings subsidence. |
