Review of Studies on Impact of Railway Subgrade Deformation on Rallast Track Structure
With the rapid development of railway industry in China,the deformation of railway subgrade during long-term service and its impact on mechanical behavior of track structure have attracted increasing attention.This paper summarizes relevant studies in recent years and analyzes the main causes of railway subgrade deformation,including natural and human factors;systematically sorts out the impact of subgrade deformation on track mechanical behavior,such as the impact of subgrade deformation on track structure deformation,train-track coupling vibration,and damage and deterioration of track structure;analyzes and points out the gaps and challenges in current studies,and prospects the future study trends in intelligent monitoring and early warning system,accurate and efficient numerical simulation technology,etc.
