摘　　要：有砟铁路是超高速铁路的重要形式之一,在适用性、建造成本及养护维修方面具有独特的优势。然而,超高速铁路有砟道床面临严峻的飞砟问题,需要采取适当的应对措施。结合相关高速铁路项目,对飞砟机理进行了阐述,并从道床结构优化、聚氨酯固化道床、轨枕结构优化、道砟覆盖网四个方面总结了超高速铁路飞砟防治技术,从而为超高速铁路的飞砟防治、有砟道床结构选型及养护维修提供参考。Ballasted railway is one of the important forms of super high-speed railway, which has unique advantages in applicability, construction cost and maintenance, however, super high-speed ballasted railway faces serious ballast flight problem, thus appropriate measures should be taken to deal with it.This study focuses on super high-speed rail project, elaborates the mechanism of ballast flight, and summarizes the super high-speed railway ballast flight prevention and control technologies from 4 aspects:ballast bed structure optimization, polyurethane curing ballast bed, sleeper shape optimization, and ballast overlay .The research results provide references for ballast flight control, ballast bed structure design and track maintenance for super high-speed railway.
