受高铁、地铁影响互通式立交方案研究——以郑州华夏大道互通式立交方案为例

Study on Interchange Scheme Affected by High-speed Railway and Metro for Zhengzhou Huaxia Avenue Interchange

随着国民经济的发展,全国高速铁路、城市轨道交通里程不断增加,综合客运枢纽较少的短板逐渐得到弥补。在此背景下,互通立交、铁路、城市轨道相互影响的情况不断增加。结合郑州华夏大道-燕都大道互通式立交相关工程,综合考虑郑机城际铁路、轨道交通17号线及工程建设时序等影响,立足流量预测数据,分别对立交主线形式和具体匝道方案进行了研究,得到了可行的立交方案。该方案较好地平衡了近远期实施、用地调整、拆迁等方面,可为其他同类型立交工程提供有益参考。

With the development of the national economy,the mileage of high-speed railways and urban rail transit has been increasing in China,and the lack of integrated passenger transport hubs has been gradually made up.In this context,the interaction of interchange,railway and urban rail is increasing.Combined with the related projects of Huaxia Avenue-Yandu Avenue Interchange in Zhengzhou,the influences of Zhengzhou-Jinan Intercity Railway,Metro Line 17 and the engineering construction time sequence,etc.are comprehensively considered.Based on the flow forecast data,the main line form and specific ramp scheme of the interchange are studied respectively,and a feasible interchange scheme is obtained.This scheme balances the short-term and long-term implementation,land adjustment and removal better,which can provide the beneficial reference for the similar interchange projects.
