【摘要】 随着我国高速公路的快速发展,人们对高速公路的关注,逐渐从简单的通达性转向了高速公路的土地占用与环境影响、使用中的安全性、服务水平等多个方面。枢纽立交作为整个高速公路网的重要组成部分,不但工程造价比较昂贵而且需要占用大量土地,其中安全性也是必须关注的重要内容,所以受到广泛关注并日益成为重要的研究课题。论文在分析现有国内互通立交资料的基础之上,结合工程中若干有代表性的互通立交的设计、建设、运营情况,借鉴国内外最新的设计理念,着重研究影响枢纽互通立交线形指标的主要因素,综合考虑交通安全,土地资源的使用等方面,深入分析互通立交线形指标与土地使用之间的关系,提出了今后高速公路建设与资源可持续发展的技术措施和具体对策。论文通过广泛的实地调研,收集了有关立交的设计图纸资料,实地观测立交匝道及变速车道上的运行车速。在详细准确的观测数据基础上,通过对比分析不同线形指标下,运行车速的变化,得出了车辆在匝道和变速车道上的运行车速变化规律。再进行理论分析和计算,研究主要技术指标的选用原则及适用条件。之后,论文研究了如何建立起一套科学合理的立交选型方案评价体系,该评价体系突出了用地指标。并使用该评价体系对某一立交做了实例分析,校核理论分析和计算结果。最后,综合本论文的研究成果,给出了针对立交设计中不足之处的改进和指标选用建议。更多还原

【Abstract】 As China’s Expressway develops quickly, people pay much attention to land use and environment impact, safety and service level of the expressway. To be an important component of the entire highway network, interchange hub project costs not only more expensive and takes a lot of land, Which also must be concerned about the safety as the important contents. That is why it received extensive attention and increasingly become an important research topic.In the analysis of existing domestic Interchanges and Some works with a representative of the Interchange design, construction, operation, the latest design concepts at home and abroad. Focus on impact of Interchange hub of the main factors. in-depth analysis of the relationship between land use and interchange specifications. The paper gave out specific measures to the future highway construction and sustainable developmentThrough extensive field research, the papers collect the relevant data of interchange design drawings, collect the operating speed on interchange ramp by field observation. on the basis of observational data, by comparing the analysis of different interchange specifications, the paper get the operating speed change low on the ramp and speed changes lanes. Then through Further theoretical analysis and computation on the main technical specifications the paper get selection principles and application conditions.After that, the paper has studied ways to establish a scientific and rational Interchange programme evaluation system. The evaluation system highlighted land use indicators. Then use the evaluation system rating a interchange to check the theoretical analysis and calculation results.Finally, the research results of this paper are given and give some suggestion for interchange design inadequacy and proposed improvements in using interchange specifications更多还原
