【摘要】：基于城市道路功能分类的横断面设计研究,是在对城市道路功能垂直和水平分类体系研究的基础上,针对不同功能道路进行横断面设计的研究。从目前国内外研究成果以及我国城市道路功能分类体系和道路横断面设计现状来看,城市道路功能分类和横断面设计存在许多不足。道路功能分类主要停留在“四级垂直”分类和道路技术指标水平分类两个层面,道路垂直功能分级体系中,快速路与主干路之间跨度较大,不利于城市路网平稳过渡发展;道路水平功能分类体系中,缺乏对不同城市规模、不同道路使用功能的分类探索;以及缺乏混合功能道路的研究。由此,引起横断面设计时道路功能定位不精准,道路设计功能与使用功能矛盾,横断面设计缺乏前瞻性,机动车道、非机动车道和人行道的布置不合理等一系列问题。所以,需要系统研究城市道路功能分类体系,重新探讨基于道路功能分类的横断面设计,进一步完善城市道路的空间形态构架功能、交通载体功能、公共空间功能、景观环境功能和城市防灾功能等。文章从道路功能垂直分类、基于技术指标的道路功能水平分类、基于城市规模的道路功能水平分类、其他道路功能水平分类和混合道路功能五个方面对城市道路功能体系进行了深入探讨,借鉴了增加快捷路完善道路功能垂直分类体系等新观点。论文主要研究了不同道路功能的横断面设计,在现有设计规范和经验的引导下探讨了各功能道路的横断面设计,并且研究了基于多级模糊综合评判的横断面评价方法。文中通过长沙市湘江新区道路功能分类,以及深南大道、芙蓉路、东方红路、万家丽路和涧湖路横断设计等实例,具体分析了基于道路功能分类的横断面设计的可行性和科学性。本文为我国城市道路横断面设计提供了有效的决策方案,对城市道路功能分类具有一定的参考价值,对城市路网规划和道路设计起到指导作用,对我国城市道路事业健康发展具有重要意义。
[Abstract]:The research of cross section design based on urban road function classification is based on the study of vertical and horizontal classification system of urban road function. From the current research results at home and abroad as well as the classification system of urban road function and the current situation of road cross-section design, there are many deficiencies in the functional classification and cross-sectional design of urban roads. The classification of road function mainly stays at the two levels of "four-level vertical" classification and horizontal classification of road technical index. In the vertical function classification system of road, the span between expressway and trunk road is large, which is not conducive to the smooth transition of urban road network. In the classification system of road level function, there is a lack of classification and exploration of different urban scale and different road use function, and lack of research on mixed function road. As a result, there are a series of problems in cross-sectional design, such as inaccurate location of road function, contradiction between road design function and use function, lack of foresight in cross-sectional design, unreasonable layout of motor lane, non-motorized lane and sidewalk, etc. Therefore, it is necessary to systematically study the classification system of urban road functions, re-explore the cross-sectional design based on the classification of road functions, and further improve the functions of urban road spatial structure, traffic carrier and public space. Landscape environment function and city disaster prevention function etc. This paper classifies the road function from the vertical classification, the road function level classification based on the technical index, the road function level classification based on the city scale. The other five aspects of road function classification and mixed road function are discussed in detail, and some new viewpoints such as increasing the expressway and perfecting the vertical classification system of the road function are used for reference. This paper mainly studies the cross-sectional design of different road functions, discusses the cross-sectional design of each functional road under the guidance of existing design codes and experience, and studies the cross-sectional evaluation method based on multi-level fuzzy comprehensive evaluation. Through the classification of road function in Xiangjiang New District of Changsha City, as well as the horizontal design of Shennan Avenue, Furong Road, Dongfanghong Road, Wanjiali Road and Jianhu Road, etc. The feasibility and scientific nature of cross section design based on road function classification are analyzed in detail. This paper provides an effective decision scheme for the cross section design of urban roads in our country, which has certain reference value for the classification of urban road functions, and plays a guiding role in urban road network planning and road design. It is of great significance to the healthy development of urban road in our country.
