高速公路预防性养护最佳时机预测及分析

在对重庆渝合、渝黔、綦万3条高速公路日常养护费用数据分析的基础上,运用回归分析建立了重庆高速公路养护费用和使用年限的关系模型,得出了重庆高速公路应进行预防性养护的最佳时机,并利用BP神经网络构建预测模型来达到预测未来重庆高速公路所需养护费用的目的。

Predication and Analysis of the Optimal Opportunity for Preventive Maintenance of Highways

Based on analysis of daily maintenance cost data of Yuhe Highway,Yuqian Highway and Qiwan Highway and by using regression analysis,the relevance model between maintenance cost and using duration of Chongqing highway was constructed,the optimal opportunity for Chongqing highways to implement preventive maintenance was obtained,and BP neural network was used to construct predictive models in order to attain the goal for forecasting the cost needed in Chongqing highway maintenance in the future.
