Comparison of Forecasting Means of Sedimentation Number of High-Rise Building
Yu Han · Journal of Tianjin Institute of Urban Construction · 2007
The common methods of the work of the settlement prediction such as exponential smoothing method,regression analysis method and the grey prediction model are used to predict the sedimentation number of high-rise building,and a forecasting experiment is conducted with the practical data.Also,the precision and the reliability of this three methods are comparative analysis from several ways.The experimental results are as follows:for the data whose downtrend is smooth,it is perfect to use the grey model method;for the settlement data which is changing slowly and the change of the later period is quite gentle,the exponential smoothing method is fit;for the settlement data whose fluctuation is obvious,the regression analysis method is better.
