【摘要】：随着近年来我国城市建设的巨大发展,城市道路的建设处于一个高速增长阶段。城市道路沥青路面在经受环境、气候等自然环境的同时,还承受着城市车辆荷载的反复作用,导致沥青路面使用性能逐渐下降。部分道路甚至已提前进入大修、改建阶段,严重影响了城市道路系统的正常运行。随着我国部分城市道路使用性能的急剧下降,城市道路沥青路面的使用性能评价与改建方案选择越来越受到人们的重视。但目前对改建方案决策并未有统一的规范,改建方案的确定大多由决策者根据经验确定。本文在借鉴已有研究成果的基础上,主要从城市道路沥青路面使用性能评价、沥青路面改建方案设计和改建方案决策方法等几个方面开展研究工作:(1)在充分分析、总结我国《城镇道路养护技术规范》和《公路沥青路面养护技术规范》中沥青路面性能评价方法的基础上,根据城市道路沥青路面破损的特点,建立了基于模糊与基因突变理论的城市道路沥青路面使用性能综合评价模型。(2)总结分析国内外沥青路面改建方案设计方法,并总结国内外改建方案的应用实例,为城市道路沥青路面改建提供可行候选方案。(3)在参考大量研究资料和总结现有沥青路面改建方案设计方法的基础上,提出了使用模糊多属性决策方法作为沥青路面改建方案选择方法,从提出沥青路面改建可行候选方案和改建方案评估体系两个方面进行改建方案决策方法的研究,建立了基于模糊与多属性决策方法确定沥青路面最优改建方案的决策模型。(4)将所建沥青路面使用性能评价模型和改建方案决策模型应用到笔者所参与的湖南芙蓉大道昭山段旧路提质改造项目中,使所建模型形象化、具体化,并验证了基于模糊与基因突变理论的沥青路面使用性能评价方法和模糊多属性决策确定沥青路面改建方案的可行性和有效性。
[Abstract]:With the great development of urban construction in China in recent years, the construction of urban roads is in a stage of rapid growth. The asphalt pavement of urban roads is subjected to the environment, climate and other natural environment, but also bear the repeated role of urban vehicle load. As a result of the deterioration of the performance of asphalt pavement, some roads have entered the stage of overhaul and reconstruction, which has seriously affected the normal operation of the urban road system. With the rapid decline of the performance of some urban roads in China, More and more attention has been paid to the evaluation of the performance of urban asphalt pavement and the selection of reconstruction scheme. The determination of reconstruction scheme is mostly determined by the decision makers according to their experience. Based on the existing research results, this paper mainly evaluates the performance of urban road asphalt pavement. Research work has been carried out in several aspects, such as the design of the asphalt pavement reconstruction scheme and the decision-making method of the reconstruction scheme. On the basis of summarizing the performance evaluation methods of asphalt pavement in the Technical Code for Urban Road maintenance and the Technical Code for maintenance of Highway Asphalt pavement, according to the characteristics of urban road asphalt pavement damage, A comprehensive evaluation model of asphalt pavement performance based on fuzzy and gene mutation theory is established. The design methods of asphalt pavement reconstruction schemes at home and abroad are summarized and analyzed, and the application examples of reconstruction schemes at home and abroad are summarized. On the basis of referring to a large number of research data and summarizing the design methods of existing asphalt pavement reconstruction schemes, this paper provides a feasible candidate scheme for the reconstruction of urban asphalt pavement. In this paper, the fuzzy multi-attribute decision method is proposed as the method of selecting the reconstruction scheme of asphalt pavement, and the decision method of reconstruction scheme is studied from two aspects: the feasible candidate scheme of asphalt pavement reconstruction and the evaluation system of reconstruction scheme. A decision model based on fuzzy and multi-attribute decision method to determine the optimal reconstruction scheme of asphalt pavement is established. The evaluation model of asphalt pavement performance and the decision model of reconstruction scheme are applied to the author's participation in Hunan Furong. In the project of upgrading the quality of the old road in Zhaoshan section of Da Dao, The model is visualized and concretized, and the feasibility and effectiveness of the evaluation method of asphalt pavement performance based on fuzzy and gene mutation theory and fuzzy multi-attribute decision making are verified.
