高等级公路预防性养护综合决策方法研究

Research on Comprehensive Decision-making Method of Preventive Maintenance for High-grade Highways

及时开展高等级公路的预养护工作对延长路面使用寿命具有重要意义;基于规范给定的路面检测指标,采用灰关联理论,通过分析判断指标与综合指标间的影响程度量化关系,建立了考虑判断指标影响权重的路面检测评价模型,为制定路面预养护综合决策方案提供了新思路;经工程案例论证,该模型能够较好地指导当下高等级公路的路面预养护决策工作。

Conducting the pre-maintenance for high-grade highways in time has great significance for prolonging the service life of the pavement.In this paper,based on the pavement detection index from the specification,by analyzing the quantitative relationship of the influence degree between judgment index and comprehensive index using grey relation theory,a pavement detection evaluation model considering the influence weight of judgment index was established,providing a new idea for making the comprehensive decision scheme of pavement pre-maintenance.Through the demonstration of engineering cases,this model can guide the decision-making of pavement pre-maintenance of high-grade highways.
