【摘要】：我国拥有广阔的国土空间,城市的地理条件也不尽相同,平原城市主要分布在我国的中部和东部以及沿海地区,因为平原城市的土地便于集中开发,所以用地布局为团块状。我国的西部城市属于典型的山地城市,山地城市通常会选择较平缓、地质条件好的用地进行用地扩展,布局呈组团式。组团式的城市布局决定了山地城市的出行距离以中长距离为主,因此构建山地城市的快速路对于提高山地城市出行效率尤为重要。快速路布局影响着城市交通出行和用地布局,然而现阶段山地城市快速路布局主要是简单的参照国内大部分城市的环射线布局模式,尚缺乏对山地城市地形、地貌的考虑,因此对山地城市快速路总体布局及评价研究显得尤为重要。首先,本文全面介绍了国内外城市快速路的研究现状以及快速路布局的主要形式。在比较分析不同地形下快速路总体布局的前提下,本文分析了山地城市的交通特性,说明了快速路对于山地城市特别是山地大城市的重要性。文中从山地城市的快速路布局、断面设置、与其它城市道路的衔接这几个方面进行了山地城市快速路规划研究。在分析了现有快速路布局方法的基础上提出了以交通区位理论和节点重要度理论为基础的山地城市快速路总体布局方法,并对其流程加以说明。其次,本文构建了山地城市快速路总体布局主要指标评价体系,并运用基于层次分析法(AHP)的模糊综合评价理论进行了山地城市快速路总体布局主要指标评价。最后,本文依照山地城市快速路线网规划布局流程,结合凯里—麻江中心城区快速路规划实例进行了分析,通过对布局主要指标的评价,得到了凯里—麻江中心城区的“十”字形快速路网总体布局。分析计算后得到的快速路网布局得到了专家组和当地政府的肯定,并选定为凯里—麻江中心城区综合交通规划中的快速路布局方案。经过实例分析和验证所得结论对我国山地城市的快速路设计有一定的借鉴意义。
[Abstract]:China has vast land and space and different geographical conditions of cities. Plain cities are mainly distributed in the central and eastern part of China as well as in coastal areas. Because the land in plain cities is convenient for centralized development, the distribution of land use is in the form of lumps. The western cities of our country belong to the typical mountainous cities. The mountainous cities usually choose the land use which is relatively smooth and the geological conditions are good for the land use expansion and the layout is in the form of group. The urban layout of group type determines that the travel distance of mountain city is mainly middle and long distance, so it is very important to construct the expressway of mountain city to improve the trip efficiency of mountain city. Expressway layout affects urban traffic travel and land use layout. However, at present, the expressway layout in mountainous cities mainly refers to the ring-ray layout model of most cities in China, and lacks the consideration of terrain and landform in mountainous cities. Therefore, it is very important to study the overall layout and evaluation of expressway in mountainous cities. First of all, this paper introduces the current situation of urban expressway research and the main forms of expressway layout at home and abroad. On the premise of comparing and analyzing the general layout of expressway under different terrain, this paper analyzes the traffic characteristics of mountainous cities, and explains the importance of expressway to mountain cities, especially mountain cities. In this paper, the expressway planning of mountainous city is studied from the following aspects: the layout of expressway, the layout of section, and the connection with other urban roads. Based on the analysis of the existing expressway layout methods, this paper puts forward the overall layout method of expressway in mountainous cities based on the traffic location theory and node importance theory, and explains its process. Secondly, this paper constructs the evaluation system of the main indexes of the overall layout of the expressway in mountainous cities, and applies the fuzzy comprehensive evaluation theory based on the analytic hierarchy process (AHP) to evaluate the main indexes of the overall layout of the expressway in the mountainous cities. Finally, according to the layout process of expressway network in mountainous city, combined with the example of Kaili-Majiang central urban expressway planning, this paper analyzes the main indexes of the layout. Get the Kaili-Majiang central urban area of the "ten" shape of the highway network overall layout. The layout of expressway is confirmed by expert group and local government, and it is selected as the expressway layout scheme in the integrated traffic planning of Kaili-Majiang central city. The conclusion obtained through the analysis and verification of examples has certain reference significance for the expressway design of mountain cities in China.
