| Abstract: | The service status of ballastless tracks in high speed railway turnouts is one of the important factors that affect train safety and operation quality.In order to ensure the operation safety of the ballastless track turnout within the design period,the current damage status of the ballastless tracks in high speed railway turnouts was investigated.Based on the structural characteristics of the ballastless tracks in the high speed railway turnouts of China,the damage forms and characteristics of the ballastless track turnouts were studied,and the damage causes were analyzed.This study is meaningful for the ballastless track design innovation in the high speed railway turnout area,and also provides guidelines for the rapid repair technology of ballastless track damage in the turnout area. |
