Abstract:Shantou High-Speed Railway Station is a key node in the main channels of the national "eight-vertical and eight-horizontal" high-speed railway network. Its drop-off platform is the core supporting facility for the high-speed railway station hub to achieve interconnection and efficient complementarity among various transportation modes. To ensure the efficient operation, the safe driving of vehicles, and the convenient travel of passengers at the high-speed railway station hub, it is crucial to construct a scientific, safe and reasonable drainage system for the drop-off platform. Focusing on the engineering practice of deck drainage design for the drop-off platform of Shantou High-speed Railway Station Hub, clarifying the engineering overview, design interfaces and key design parameters, the drainage engineering design contents are set forth in detail, and the critical design essentials are discussed. The aim is to provide the strong support and useful references for the deck drainage design of drop-off platforms in similar domestic projects, thereby promoting the rationalization, scientization and multi-ecological development of the drainage system design for drop-off platforms at high-speed railway station hubs.
