基于FAHP的高速公路预防性养护方案比选

Comparison and Selection of Preventive Maintenance Schemes for Expressways Based on FAHP

预防性养护是一种改善路面使用性能、延长路面使用寿命、降低全周期养护成本的有效养护措施。预防性养护方案的选择要同时考虑道路管理者的需求和方案的应用效果,具有较大的不确定性。为了科学地选取高速公路预养护方案,基于模糊层次分析法,考虑技术效果、施工可操作性和经济性3个方面的9个因素,以上海两条高速公路工程为依托开展案例分析,为同类型预防性养护方案比选提供参考。

The preventive maintenance is an effective maintenance measure to improve the pavement service performance,extend the pavement service life and reduce the maintenance cost of the whole cycle.The choice of preventive maintenance schemes should consider the needs of road managers and the application effect of schemes,which has the larger uncertainty.In order to scientifically select the pre-maintenance scheme of expressway,the fuzzy analytic hierarchy process is used to consider nine factors from three aspects of technical effect,construction operability and economy.Relying on two expressway projects in Shanghai,the cases are analyzed to provide the reference for the comparison and selection of similar preventive maintenance schemes.
