摘要
在路堤沉降预测中,线性模型是应用最为广泛的模型之一。但是随着观测信息的丰富,常规的线性模型的不足凸现,影响了模型的精度,为了克服常规模型的缺点提出了滑动线性回归模型。滑动线性回归模型要求参与建模的数据个数保持不变,新观测的数据取代旧有的数据,从而获得了新的模型参数,通过实例验证,得到了理想的结果。
Linear regression model is one of the most widely used method in the predication of embankment settlement. Accompanying with rich investigation information, the disadvantages of traditional linear model stand out extremely, so the accuracy of prediction＇is reduced. To overcome deficiencies in the traditional model, regression linear dynamic model is put forward. This model requests that the number of data used to make model is kept unchanged, new data replaced the old data, so the new parameter is gained. Ideal result is gotten through the instance.
