Development Status and Prospect of Deformation Monitoring Techniques for High-Speed Rails

摘要

This paper introduces the principles, technical and performance characteristics of subgrade and track deformation monitoring methods for high-speed rails such as hydrostatic leveling, hydraulic settlement gauge and track geometry car based on the subgrade and track deformation requirements for high-speed rails and the current application status in relevant engineering monitoring fields. Furthermore, development trends of the monitoring techniques are prospected.
