首先,分析中央门立体交叉口在南京市所处的地位,明确相交道路等级,并从南京总体规划与布局、干道系统的布置来分析相交道路近期与远期的性质与任务。其次,采用逻辑斯蒂、对数曲线、幂函数、复利公式等与工农业总产值的增长推算出远景期交通量。从而,根据相交道路的性质、远景交通量、设计特点的要求,针对周围环境、地形、地质、水文等情况,提出五个不同类型的方案,并简要说明每一方案的交通运行情况、技术与管理措施和设计特征等。最后,从适应性、与周围环境配合、通行能力,行车速度与安全性、总投资值、总效益值、效益比、施工难易程度、实现可能性和占地面积等方面的指标进行综合分析,得出最优的方案。
First of all, it analyzes the position of the intersection of the Central Gate in Nanjing, clarifies the grade of the road intersected, and analyzes the nature and tasks of the short-term and long-term road intersections from the overall planning and layout of Nanjing and the layout of trunk roads. Secondly, using Logistic, logarithmic curve, power function, compound interest formula and the growth of gross output value of industry and agriculture, the long-term traffic volume is deduced. Therefore, according to the nature of the intersecting roads, traffic volume and design features, five different types of scenarios are proposed according to the surrounding environment, topography, geology and hydrology, and a brief description of each scenario of traffic operation, technology and Management measures and design features. Finally, a comprehensive analysis is made of the indicators of adaptability, coordination with the surrounding environment, traffic capacity, traffic speed and safety, total investment value, total benefit value, benefit ratio, degree of construction difficulty, possibility of realization and land occupation , Come to the best solution.
