【摘要】：近年来，我国高速公路事业不断发展壮大，至2013年底，高速公路里程已突破10万公里。路网规模的不断扩大、区域性路网的初步形成，体现了我国高速公路发展日趋成熟，工作重心应逐渐从建设转向养护管理。高效的养护管理有利于保持高速公路良好的使用状态和服务水平，养护工区的布局合理与否将决定养护工作是否能高效率完成，这对于延长道路使用寿命具有十分重要的意义。基于此，本文根据道路病害类型、养护任务及路网布局，将养护工区分成三级，形成了不同功能要求、差异化配置、不同等级的养护工区，给出了具体的分级标准、功能要求以及配置标准，并对养护工区的经济性进行了分析。针对养护工区布局中涉及的集合覆盖问题建立了数学模型，综合考虑了选址的各种费用及具有一定技术性限制条件等问题，提出了运用时间限制性约束条件、最短路求解和贪婪启发式的组合算法。以陕西省高速公路网进行实例分析，，结合调研得到陕西省沥青混合料的温降系数，通过理论计算对高速公路养护工区进行了合理布局。针对陕西省目前高速公路养护管理模式的弊端，提出了符合陕西省高速公路健康发展的养护管理新模式。提出了解决我国高速公路养护问题的初步设想，进一步分析了新的高速公路养护工区布局和管理模式，并对其进行了社会效益和经济效益评价。
[Abstract]:In recent years, China's expressway industry has been growing, by the end of 2013, highway mileage has exceeded 100000 km. With the expansion of network scale and the initial formation of regional road network, the development of expressway in China is becoming more and more mature, and the focus of work should be gradually shifted from construction to maintenance management. Efficient maintenance and management is helpful to maintain the good service level of expressway, and whether the layout of maintenance area is reasonable or not will decide whether the maintenance work can be completed efficiently or not, which is of great significance for prolonging the service life of the road. Based on this, according to the types of road diseases, maintenance tasks and road network layout, the maintenance work area is divided into three levels, forming different functional requirements, different configuration, different grades of maintenance areas, and the specific classification standard is given. Function requirements and configuration standards, and the economy of the maintenance area are analyzed. In this paper, a mathematical model is established to solve the problem of collective coverage in the layout of maintenance area. Considering the various costs of site selection and some technical constraints, the time constraint condition is put forward. Shortest path solving and greedy heuristic combination algorithm. Taking the highway network of Shaanxi Province as an example, the temperature drop coefficient of asphalt mixture in Shaanxi Province is obtained by combining investigation and investigation, and the reasonable layout of highway maintenance area is carried out through theoretical calculation. In view of the malpractice of the current expressway maintenance management mode in Shaanxi Province, a new maintenance management model which accords with the healthy development of the highway in Shaanxi Province is put forward. This paper puts forward a tentative plan to solve the problem of expressway maintenance in China, further analyzes the layout and management mode of expressway maintenance area, and evaluates its social and economic benefits.
