Abstract：The subgrade isan essntial structural foundation in high-speedrailway engineering，and itslong-term stability directlyaffects railway transportationsafety.With continuously increasing train speedsand axle loads， cumulative setlement of subgrades under dynamic loading is becoming increasingly prominent. Consequently，it has emerged as a critical interdisciplinary research hotspot across railway enginering， geotechnical engineering， and engineering mechanics.This paper reviews domestic and international research achievements regarding cumulative setlementofsubgrades subjected to high-speed train loading.Specifically，itsummarizes recent developments in experimental investigations，theoretical analyses，and influencing factors related to cumulative setlement，highlighting the complexityand key technicalchallenges associated with long-term subgrade deformation. Moreover，the paper outlines future research directions，including examining the efcts of intermitent loading on long-term deformation，as well as investigating the particle breakage mechanism of subgrade fillmaterials and its impact on deformationbehavior.This review aims to provide theoretical support for the design and opti

mization ofhigh-speed railwayinfrastructures.
