上跨马磁铁路节点设计方案比选分析

Comparative analysis on over-crossing Maci railway joint design scheme

结合鼓清路的工程概况,分析了上跨马磁铁路的总体设计原则,并提出了梯道、地道、匝道三种上跨方案,从交通功能、施工难度、运营维护、造价等方面,比选了各种方案的优缺点,最终选择主线上跨桥+人非下穿地道作为推荐方案。

Combining with Guqing road engineering conditions, analyzes general design principles of over-crossing Maci railway, puts forward three kinds of over-crossing scheme of stairway, tunnel and ramp, compares their merits and defects from aspects of traffic functions, construction difficulty, operation maintenance and cost, and finally selects major over-crossing bridge ＋ under-passing tunnel as the recommended scheme.
