In this destructive ballastless track slab experiment, under the action of a reaction wall, a four-point synchronous load was gradually applied to measure the curve relationship between force and displacement at four points. The system ultimately chosen was a four-point 2.2KW variable frequency control synchronous lifting hydraulic system, equipped with four 100-ton hydraulic jacks (150mm stroke, 280mm body height), eight 30-meter main oil hoses, and 30-meter sensor signal detection devices. Additionally, four sets of 100-ton load cells were included for precise force feedback.
