【摘要】：在道路运营过程中特别是收费运营末期的高速公路,在保证路面运营时期内提供足够的服务水平的同时,实现养护资金效益最大化是一个需要系统考虑解决的矛盾问题。依据现行养护管理体系和设计标准,通常需要对现有公路技术状况进行全面系统的评价,再结合项目实际营运特点进行选择科学合理的养护方案决策。本文结合西安至铜川高速公路2015年路面养护工程,对于运营末期沥青路面养护方案决策进行了探讨。路面养护决策是路面管理的核心内容,养护方案是否科学合理将直接影响到养护成本、后期项目使用状况和服务水平。本文的养护决策采用分阶段决策法,第一阶段初步决策判断各路段的养护措施类型,第二阶段根据各养护措施类型选择对应层次分析法模型进行决策。结果显示,层次分析法是进行养护决策的有力手段,它可以对人们的思维过程进行加工整理,按照系统分析问题的方法进行科学决策。合理选择影响养护决策的准则并建立好的层次结构是非常关键的,它直接影响能否最终得到最优决策方案。
[Abstract]:In the course of road operation, especially in the end of toll collection operation, it is a contradiction that needs to be solved systematically to ensure the sufficient service level during the pavement operation period, and to maximize the benefit of maintenance funds at the same time. According to the current maintenance management system and design standards, it is usually necessary to make a comprehensive and systematic evaluation of the existing highway technical conditions, and then to select a scientific and reasonable maintenance scheme decision based on the actual operating characteristics of the project. Based on the pavement maintenance project of Xi'an to Tongchuan Expressway in 2015, this paper discusses the decision of asphalt pavement maintenance scheme in the end of operation. Pavement maintenance decision is the core content of pavement management. Whether the maintenance scheme is scientific and reasonable will directly affect the maintenance cost, late project usage and service level. The maintenance decision in this paper is based on the method of stage decision. The first stage makes a preliminary decision to judge the types of maintenance measures in each section, and the second stage selects the corresponding analytic hierarchy process (AHP) model for decision-making according to the types of maintenance measures. The results show that Analytic hierarchy process (AHP) is a powerful means to make maintenance decision. It can process people's thinking process and make scientific decision according to the method of systematic analysis. It is very important to reasonably select the criteria that affect the maintenance decision and establish a good hierarchical structure, which directly affects whether the optimal decision scheme can be obtained at last.
