Vibration Behavior and Reinforcement Effect Analysis of the Slab Track-Subgrade with Mud Pumping under Cyclic Dynamic Loading: Full-Scale Model Tests

<div>The variation of vertical vibration acceleration of the model with the number of loading cycles. (a) The upper layer of the subgrade bed in normal condition (stage 1). (b) The upper layer of the subgrade bed in saturation (stage 2). (c) The model after mud pumping reinforcement (stage 3).</div>
