郑许市域铁路下穿机场段线路方案研究

Title: study on route of zhengzhou to xuchang inter-city railway cross the airport area

郑州机场至许昌市域铁路(以下简称"郑许市域铁路")是实现郑许融合发展,强化中心城市辐射能力的重要交通支撑。线路途经机场片区,走向受机场航站楼群、既有跑道及灯光带、既有围护结构及航空货运枢纽战略规划影响较大。综合考虑线路条件、施工风险、工程投资、对机场后期建设影响等因素,推荐下穿既有跑道方案。经过数值分析,推荐方案下穿跑道处沉降可控制在10mm之内。

Zhengzhou to Xuchang Inter-city Railway is an important railway engineering to integrate the development of Zhengzhou and Xuchang,which also can strengthen the radiation ability of central city.The route passes through the airport area,and it is greatly influenced by airport terminal buildings,existing aircraft runway and lighting belt,existing enclosure structure and strategic planning of air cargo hub.Considering route conditions,construction risks,engineering investment and the impacts on the coming airport constructions,crossing route under the existing aircraft runway is recommended.Through numerical analysis,the settlement of crossing route position can be controlled within 10mm.
