As the loading time continues, the load-displacement curves of the specimens with different buried depths appear to be quite different, and the specimens with large buried depths appear obvious "vibration rebound" phenomenon.
With the continuous loading time, the load-displacement curve of different buried test pieces is quite different, and the phenomenon of "vibration rebound" appears in large buried test pieces.
As the loading time continues, the load displacement curves of the specimens with different buried depth show great differences, and the specimens with large buried depth show obvious "vibration rebound" phenomenon.<br>
