摘要：针对目前公路养护质量评定方法的综合指标计算模型中设施权数为定值的问题，本文设计了一种新的加权方法，即等效长度加权法，该方法用等效长度作为设施的权数，解决了固定权数不能反映设施数量的问题，并且既能用于单一设施评价又可用于多设施综合评价。

Equivalent Length-Weighted Method and Its Application on Evaluation of Highway Technology Status

WANG Guo-ying  CHEN Zhang  SUN Li-jun

Abstract: Aiming at the problem of fixed Weight in the highway maintenance comprehensive evaluation model, a new method called “equivalent length-weighted method” was developed. The method utilized equivalent length as weight of highway infrastructures, which could consider essentiality and magnitude of infrastructures and could be used to evaluate both a single infrastructure and the integration of multi-infrastructures.
