基于回归分析方法的桥梁技术状况预测

Prediction of Bridge Technology Condition Based on the Regression Analysis Method

以北京高速公路桥梁历年技术状况评定数据为基础,利用回归分析方法拟合桥梁技术状况衰退模型,进而预测桥梁技术状况发展趋势.通过对京藏高速公路桥梁技术状况的预测,论证了基于回归分析方法预测桥梁技术状况的可行性.

In this paper, on the basis of the technical condition evaluation data of Beijing highway bridge over the years, the regression analysis method is used to fit the regression models of bridge technical condition, and to predict the development trend of the technical condition of bridge. Through forecasting the technical condition of Tibet Expressway Bridge in Beijing, it proves the feasibility of the method of regression analysis to predict the development trend of the bridge technical condition.
