城市道路与高铁线路交叉工程设计方案研究

随着高铁建设的加速发展，位于城区段的高铁线路与城市道路的交叉关系问题日趋突出，在道路方案设计过程中需要处理好两者之间的交叉关系，以保障高铁运营及结构安全。以合肥市繁华大道与玉兰大道及合安高铁肥西联络线交叉工程为例，提出了两种节点分离式立交设计方案，从方案可行性分析着手，结合对铁路的影响、施工难度、景观效果及工程造价等方面进行综合比较，确定了最优方案。

Study on Design Scheme of Intersecting Engineering for Urban Road and High-speed Railway Line

With the accelerated development of high-speed railway construction, the intersecting relationship between high-speed railway line and urban road located in urban area is becoming increasingly prominent. In the process of road scheme design, it is necessary to deal with the intersecting relationship between the two to ensure the operation and structural safety of high-speed railway. Taking the intersecting project of Fanhua Avenue, Yulan Avenue and Feixi Connecting Line of Hefei-Nanchang High-speed Railway in Hefei as an example, two design schemes of node separated interchange are proposed. Starting from the feasibility analysis of the scheme, combined with the impact on the railway, construction difficulty, landscape effect and engineering cost, the optimal scheme is determined after the comprehensive comparison.
