Generally, the maximum height S p decreases with the increase of shear times, as in the four groups of interfaces with 4 MPa normal stress (AD-1, AD-2, AD-3 and BD-1); however, S p corresponding to first shearing is greater than that before the test and then shows a decreasing trend with the increase of shear times.
