【摘要】：近年来,高速公路建设步伐的加快和养护任务的加剧使高速公路养护管理面临着巨大的挑战。就湖南省而言,现已应用的路面养护管理系统基本上实现了高速公路养护管理的信息化,但在高速公路的小修养护决策过程中,仍存在小修养护适用范围不明确、养护费用测算粗放等问题,并且养护管理过程也不尽规范。在这种背景下,开展小修养护适用性及经费测算方法研究,开发一套高速公路小修养护精细化管理系统,将极大的提高小修养护决策水平,实现高速公路养护管理的精细化。本文主要研究工作如下:①根据路面结构组合形式、结构厚度和混合料类型等的不同进行湖南省高速公路沥青路面典型路面结构形式的划分。结合典型路面结构形式的代表性路段的路面病害统计数据,确定了湖南省高速公路沥青路面的典型病害。②结合沥青路面典型病害特征,指出仅采用现行路面破损状况指数PCI进行路面破损状况评价的不足。提出PCI的三个辅助分项指标,并建立了基于可拓理论的路面破损状况评价方法。③围绕高速公路沥青路面小修养护适用范围不明确这一问题,开展了小修养护适用性研究,并提出了一种将单维修指标阈值与多维修指标共存时PRI值相结合进行小修养护适用范围的确定方法。④对于路基、沿线设施及绿化等小修养护对象,提出了以已通车高速公路的历年路基、沿线设施及绿化维修经费的平均值作为第6年小修经费的基准值,并综合考虑交通流量、通车年限及地质地形条件的影响,进行基准值的修正的费用测算方法。对于沥青路面,提出了基于病害测算法的路面小修费用的测算模型。⑤基于以上的研究,进行小修养护精细化管理系统设计和开发,实现了高速公路养护精细化管理的目标。
[Abstract]:In recent years, with the acceleration of expressway construction and the aggravation of maintenance task, expressway maintenance management is facing great challenges.As far as Hunan Province is concerned, the existing pavement maintenance management system has basically realized the informationization of expressway maintenance and management, but in the decision-making process of minor maintenance and maintenance of expressway, the scope of application of minor maintenance is not clear.The maintenance cost measurement is extensive, and the maintenance management process is not standardized.Under this background, the research on the applicability and cost calculation method of minor maintenance and the development of a set of fine management system for minor maintenance of expressway will greatly improve the decision-making level of minor maintenance and realize the refinement of highway maintenance management.The main research work of this paper is as follows: 1. According to the pavement structure combination form, the structure thickness and the mixture type, the typical pavement structure form of Hunan expressway asphalt pavement is divided.Based on the statistical data of pavement diseases in typical road sections, the typical diseases of asphalt pavement in Hunan Province are determined. 2. Combined with the characteristics of typical diseases of asphalt pavement.It is pointed out that only the current pavement damage condition index (PCI) is used to evaluate the pavement damage condition.Three auxiliary sub-indexes of PCI are put forward, and the evaluation method of pavement damage condition based on extension theory is established. 3. The applicability of minor repair maintenance of expressway asphalt pavement is studied according to the problem that the applicable scope of minor maintenance of asphalt pavement is not clear.This paper also puts forward a method of determining the applicable scope of minor repair maintenance when the threshold value of single maintenance index and the PRI value of multiple maintenance indexes coexist. 4. For minor maintenance objects such as roadbed, facilities along the line and greening, etc.Taking the average expenditure of roadbed, facilities along the highway and greening maintenance funds as the benchmark value for minor repairs in the sixth year, and considering the influence of traffic flow, service life and geological and topographic conditions, the paper puts forward that the average value of funds for minor repairs in the past years of the highway has been opened to traffic.The method of calculating the cost of revising the base value.For asphalt pavement, the model of calculating pavement minor repair cost based on disease calculation method is put forward. Based on the above research, the fine management system of minor repair maintenance is designed and developed, and the goal of fine maintenance management of expressway is realized.
