市政道路与铁路立体交叉设计影响因子分析

Analysis of Influencing Factors for Grade Separation Design between Municipal Roads and Railway Lines

市政道路与铁路的交叉方案设计既要保证铁路的正常营运,也要保证道路的功能属性不受交叉方案的影响,更要保证工程施工安全、质量及进度。工程规划设计前期选择合理的交叉方案成为道路建设的重要控制性因素。以实例入手探讨了市政道路与铁路立体交叉在前期规划、方案设计以及施工过程中的影响因子。

For the design of the grade separation between municipal roads and railway lines, it should be ensured that the railway can operate normally and the road performance would not be affected by the grade separation scheme. And the safety, quality and the progress of the construction should be guaranteed as well.Therefore, it is a crucial controlling factor for road construction to select the rational scheme in the early stage of the engineering. Based on practical examples, this paper discussed the influencing factors in the design, planning,and construction stages of the grade separation scheme between the municipal roads and railway lines.
