Analysis of the Influence of Groundwater Level Fluctuation on Karst Soil Cave Collapse

Figure 12

Deformation of overlying soil during water level droping. (a) Variation of cave roof displacement with time steps during the dropping of different initial water levels. (b) Variation of cave roof displacement under different initial water levels dropping. (c) When the initial water level height is 100 mm, the displacement of the roof of cave and the displacement of the overlying soil variation with time steps.
