The dynamic stress response of the lower course by moving-vibrating compaction on semi-rigid base was analyzed to judge whether it caused early wreckage to the lower course.
Train velocity has little influence on the dynamic stress and dynamic deformation of subgrade bed, but has obvious influence on vibrating velocity and vibrating acceleration.
列车运行速度对振动速度、振动加速度的影响比对动应力、动变形的影响更显著。

The CD type vibrating-wire force anchor is developed, which is made up of a few vibrating-wire stress gauges.
