【摘要】：随着中国——东盟博览会永久落户南宁,南宁必将成为一个国际化大都市,而南宁市五象新区的建设,作为开发广西北部湾经济区的国家战略,是南宁市向南发展、向海靠拢、全面融入广西北部湾经济区开放开发、打造区域性国际城市的重要平台和前沿阵地。因此,平乐大道与玉洞大道互通式立交是五象新区核心区的一个重要交通节点,对于完善城市交通路网意义重大。论文首先介绍了该互通式立交区域的地形、地貌、地质、气候、水文、地震等自然条件和道路、沟渠、管线、建筑物等基础设施,并在前期研究阶段,介绍了在工可阶段及设计阶段,两种方案的比选论证工作;在此基础上分析了该互通式立交区域道路、用地、公交、轨道等的规划及交通量预测情况;结合互通式立交总体设计原则,分析互通式立交定位与选型的影响因素,对互通式立交的方案进行比选,确定了互通式立交推荐方案;并提出了推荐方案的平纵横设计、路基设计、路面结构设计、桥梁设计以及施工方案。在本互通式立交方案研究过程中,得到如下结论:(1)在方案前期研究中,应当对现场自然条件以及沿线城市设施进行详细地调查和论证;(2)在方案前期研究完成后,应对互通式立交区域附近的道路交通量进行预测,以便之后进行设计;(3)在进行专业工程设计之前,应当考虑互通式立交定位与选型要素,确定出互通式立交的推荐方案;(4)在进行专业工程设计时,应当充分考虑各方面因素,尤其应当考虑工程地质条件,按照步骤一步一步进行设计。
[Abstract]:With the permanent settlement of the China-ASEAN Expo in Nanning, Nanning will certainly become an international metropolis. The construction of the Wuxiang New area of Nanning City, as a national strategy for developing Guangxi's Beibu Gulf Economic Zone, is the development of Nanning to the south and to the sea.Fully integrated with Guangxi Beibu Gulf Economic Zone open development, to create an important regional international city platform and forward position.Therefore, the interchange between Pingle Avenue and Yudong Avenue is an important traffic node in the core area of Wuxiang New area, which is of great significance to the improvement of urban transportation network.The paper first introduces the terrain, geomorphology, geology, climate, hydrology, earthquake and other natural conditions and roads, ditches, pipelines, buildings and other infrastructure in the interchange area, and in the early stage of research.This paper introduces the comparison and demonstration of the two schemes in the stage of construction and design, and analyzes the planning and traffic volume prediction of the interchange area road, land use, public transport, track, etc.Combined with the general design principle of the interchange, the influence factors of the location and type selection of the interchange are analyzed, the scheme of the interchange is compared and selected, the recommendation scheme of the interchange is determined, and the horizontal and horizontal design of the recommendation scheme is put forward.Subgrade design, pavement structure design, bridge design and construction scheme.In the course of the study of the interchange scheme, the following conclusions are drawn: 1) in the preliminary study of the scheme, the site natural conditions and the urban facilities along the route should be investigated and demonstrated in detail) after the completion of the preliminary study,The traffic volume in the vicinity of the interchange area should be forecasted so that the design can be carried out later. Before the professional engineering design is carried out, the location and selection elements of the interchange shall be considered.In the course of professional engineering design, all factors should be fully taken into account, especially the engineering geological conditions, and the design should be carried out step by step according to the step by step.
