高速公路养护经费测算方法研究

Study on Evaluating Method of Expressway Maintenance Outlay

根据指标体系的确定原则,构建了高速公路养护维修率的指标体系;结合调研数据特点,提出养护维修率的定量预测方法及6个计算变量;建立了基于综合路况的公路公里养护维修费用计算模型,并提出模型中的关键参数基准值和权重系数的确定方法。实例验证结果表明,本研究方法可为养护经费的合理分配提供决策依据。

Based on the principle to determine index system, the index system of expressway maintenance ratio is established. Combining with the characteristic of the raw data surveyed, the prediction method for motorway maintenance ratio and six computational variables are brought forward. The expressway maintenance per mile fee mode based on the integrative pavement status is finished, and the exact way to achieve the key variables such as benchmark value and weight-coefficients is put forward, in an actual case, the results indicate that the conclusion can provide basis for rational allocation of maintenance outlay.
