摘要
建筑物的沉降监测数据序列具有趋势变化和随机变化的特点 ,本文针对两种变化项的特点分别建立相应的数学模型 ,再将其组合起来建立综合数学模型 ,从总体上把握沉降数据序列的变化规律。实例计算分析表明 ,此方法具有较高的拟合精度和预测能力 。
Settlement observation data series for building has two characteristics of tendency fluctuation and stochastic fluctuation. In this paper, a comprehensive model is presented in which the two parts of time series are considered. An example indicates that the analyzing result is more realistic and has practical value.
