摘　　要：市政道路下穿高铁的设计需要综合考虑多方面因素。下穿方案要考虑桥下净空、地质条件、施工条件等。平面线形方案设计要确保道路布局合理、交通流畅,并提供足够的视距和横向通行空间。路基处理方案需要考虑地质条件、土壤承载力等因素,确保路基的稳定性和安全性。为保证高铁运营和市政道路交通的安全,下穿区域需要设置相应的防护设施,如护栏、防撞墙等。文章系统地分析了市政道路下穿高铁设计关键技术要点,以佛山市高明区下穿在建珠肇高铁市政道路项目为例,探讨了市政道路下穿方案、平面线形方案、路基处理方案、防护设施设计方案等关键设计技术方案,供同类项目参考借鉴。The design of municipal roads underpass high-speed railways require considering multiple factors.The underpass solution needs to take into account factors such as the clearance beneath the bridge,geological conditions,and construction requirements.The design of the horizontal alignment must ensure a rational road layout,smooth traffic flow,and sufficient visibility and lateral space for vehicles.The embankment design should consider geological conditions and soil bearing capacity to ensure stability and safety.To ensure the safety of both the high-speed railway and municipal road traffic,corresponding protective measures need to be implemented in the underpass area,such as guardrails and crash barriers.Systematically analyzes the key technical points for designing municipal roads that pass under high-speed railways.Taking the example of the underpass project of the Zhuzhao high-speed railway in Gaoming District,Foshan City,it explores key design technical solutions including underpass schemes,horizontal alignment designs,embankment treatments,and protective facility designs,providing reference for similar projects.
