摘要
道路表面状况直接影响到日常出行,是道路养护决策的主要依据之一。但当前道路状况评价模型中部分评价指标的原始数据不易获取,且计算过程较为复杂,严重影响了模型的实际应用。本文以北京市石景山区的道路养护数据为例,通过对现有路面综合状况评价指标的调查和分析,在主成分分析法基础上对模型进行简化,重新确定了各项指标权重,减少了计算量。最后利用模型计算结果与道路使用年份数据对比分析,得出了石景山区的道路养护优先级,为道路养护提供了科学建议。
The surface condition of road has direct influence on daily trip,and it is one of the main basis of road maintenance decision.But in the current road condition evaluation model,the original data of some evaluation indexes are not easy to obtain,and the calculation process is more complex,which seriously affects the actual application of the model.Taking the road maintenance data in Beijing,Shijingshan District as an example,this paper simplifies the model on the basis of principal component analysis by investigating and analyzing the existing comprehensive evaluation index of road surface.The weight of each index is redefined,and the amount of calculation is reduced.Finally,by comparing the model calculation results with the road service life data,the priority of road maintenance in Shijingshan District is obtained,which provides scientific advice for road maintenance.
