Multilevel Collapsibility of Loess under Irrigation in Jinya Town, Gansu Province, China

Figure 8

The collapsibility velocity of each benchmark. Because the irrigation process was interrupted for three days, the collapsibility velocity curve of the irrigation appears different from the typical curve, that is, there is a peak value before and after the interruption. The second peak is smaller than the first one, and the difference between these two peaks decreases with the increase of depth.
