High一speed Rail Track Regularity Keeping Techniques

      SWJTU develop the techniques of precision measurement for geometrical parameters and quick fine adjustment of HSR track, the monitoring and controlling techniques of foundation deformation of special section track, and the techniques of track regularity dynamic detection and low dynamic keeping. The HSR track regularity keeping system, featured by line to point measurement and controlling, up to down deformation adjustment and controlling, and static to dynamic detection and controlling, is established. The system has been successfully applied to more than 10 HSR lines, achieving significant economic benefits of over 500 million yuan and making safer HSR operation and more comfortable riding experiences.
