摘要
Abstract
Preventive maintenance can prolong the service life of road surfaces and reduce capital investment.Cur-rently,the benefit evaluation focuses on road conditions and tends to be result oriented.Under the new situation of social development,it is worth studying how to comprehensively consider the social impact of construction site man-agement and traffic congestion on the basis of road conditions,so as to balance social factors and process orientation in the benefits evaluation process of preventive maintenance.The research period of existing preventive maintenance evaluation models is mostly preventive maintenance in the year,which only evaluate its short-term benefits but ig-nore long-term ones.Therefore,the value engineering theory and functional equilibrium model were applied.Com-bined with entropy weight method and analytic hierarchy process(AHP),a new and long-term evaluation system was established by comprehensively considering three factors of road condition level,traffic impact and on-site manage-ment.The functional equilibrium model was applied to analyze 9 road samples in Beijing,and the feasibility and ef-fectiveness of the evaluation method were verified by the IFS-TOPSIS evaluation results.Research showed that the benefit evaluation model of urban road preventive maintenance based on value engineering and functional balance can accurately evaluate the long-term comprehensive benefits of preventive maintenance.The key to exert the ad-vantages of preventive maintenance is the selection of opportunity.关键词
