网架结构变形的灰色预测

对网架结构特征点进行等时刻观测,利用灰色理论建立网架结构变形的预测模型,对网架结构的变形发展趋势进行预测分析,将预测结果与实际观测结果进行比对,确定灰色理论预测模型适用于网架结构的变形观测。在预测的精度分析中,采用残差检验的方法,通过对预测变形数据的绝对误差和相对误差进行系统分析,认为灰色理论的预测模型对网架结构的变形发展趋势具有较可靠的预见作用。

Forecast about deformation of grid structure by using grey system theory

By observing the feature points of grid structure at the same time interval,The grey system was used to set up the deformation model of grid structure, and then the development trend of the grid structure was forecasted and analyzed. By comparing the results of the forecast and the practical observation, it believed that the gray theory prediction model was suitable for the grid structure of the deformation observation. The forecast accuracy was analyzed by using residual inspection method. The grey system theory prediction model was considered to be reliable and predictable role for the deformation trend of grid structure by analyzing the absolute error and relative error of the deformation prediction data.
