高速公路综合管理指标的分析和设计

Analysis and Design on Integrated Management Indicators of Expressway

高速公路业主管养成本和效益的界定是个尚待解决的复杂问题,针对这个问题,基于实际情况和简约原则,通过分析概念、建立管养成本表达式,得到了确定性管养的重要性系数以及随机性日常养护系数等重要参数,提出了通过立项指标、养护工程使日常养护向“轻”级并通过效益指标监管保持养护等级的动态优化成本效益管理模式。以成本分析为基础,建立成本和效益的对应关系,得出了确定性、半确定性、随机性日常养护的效益指标。

The definition of management and maintenance cost and benefit of expressway is the complicated pending problem.Aiming the problem and based on the reality and simple principle,by analyzing the concept and establishing the expression of management and maintenance costs,the important parameters such as the importance coefficient of certainty management and the randomness routing maintenance coefficient are obtained,and the dynamic cost-effect optimization managing mode is put forward,which is a process tending to"light"maintenance grade through project-decision indicators,maintenance engineering and the supervision of effect indicators.Based on the cost analysis,the corresponding relation between cost and effect is set up to obtain the benefit indicators of certainty,half-certainty and randomness routing maintenance.
