【摘要】：自改革开放以来,国家经济飞速发展,对高速公路建设投入的资金比重大幅度增加,预计到“十二五”末,国家高速公路网将基本建成。随着时间的推移,公路交通量及交通荷载不断增加,路面的使用性能随着交通量及使用年限的增加呈现衰减趋势,产生严重的早期性能破坏；需要在一定时期对路面采取合理而有效的养护措施来保证路面行车的安全舒适性能。为了在有限的资金条件下合理的分配养护资金,使路面使用性能维持在一个令人满意的水准,并且能够产生最大的经济效益,需要对路面的养护决策进行深入的研究。随着我国高速公路建设事业的发展和高速公路网的逐渐形成,高速公路的养护管理问题显得越发突出和重要。我国高速公路的养护管理工作起步较晚,目前尚缺乏统一的养护技术标准和规范,对于不同的区域高速公路的养护管理模式也有所不同。文章主要对路面养护管理系统中的路面使用性能的评价、预测及决策三大部分进行研究。在路面性能评价方面,提出模糊评价法对路面使用性能进行综合评价,应用几何加权法对PQI值进行计算,运用层次分析法确定权重值；在对路面的使用性能进行预测方面,在灰色预测基础上结合马尔可夫状态转移矩阵,建立改进残差灰色预测模型。养护决策方面,引入灰色关联度对路段养护的实施进行排序,确定在资金有限条件下路段养护的先后顺序；对养护路段拟采用方案的多个控制指标采用理想点和负理想点模型排序,确定最佳的养护方案。
[Abstract]:Since the reform and opening up, the national economy has developed rapidly, and the proportion of funds invested in highway construction has increased greatly. It is expected that by the end of the 12th Five-Year Plan, the national highway network will be basically built. With the passage of time, the traffic volume and traffic load increase continuously, and the pavement performance decreases with the increase of traffic volume and service life, resulting in serious early performance damage. It is necessary to take reasonable and effective maintenance measures to ensure the safety and comfort of the road surface in a certain period of time. In order to allocate the maintenance fund reasonably under the condition of limited funds, to keep the pavement performance at a satisfactory level and to produce the greatest economic benefit, it is necessary to make a thorough study on the maintenance decision of the pavement. With the development of expressway construction and the formation of highway network, the maintenance and management of expressway becomes more and more important. The maintenance and management of freeway in our country started late, and there is still a lack of uniform maintenance technical standards and norms at present, and the maintenance and management modes of different regional freeways are also different. This paper mainly studies the evaluation, prediction and decision of pavement performance in pavement maintenance management system. In the aspect of pavement performance evaluation, the fuzzy evaluation method is put forward to evaluate the pavement performance synthetically, the geometric weighting method is applied to calculate the PQI value, the analytic hierarchy process is used to determine the weight value, and the pavement performance is forecasted. On the basis of grey prediction, an improved grey prediction model of residual error is established by combining Markov state transition matrix. In the aspect of maintenance decision-making, the grey correlation degree is introduced to sort the implementation of road maintenance, and the sequence of road maintenance under the condition of limited funds is determined. The optimal maintenance scheme is determined by using ideal point model and negative ideal point model.
