Influence of Rainfall-Induced Erosion on the Stability of Sandy Slopes Treated by MICP

Figure 11

(a) and (c) 3D surface views of the sand surface before rainfall-induced erosion; (b) and (e) 3D surface views of sand surface after 24-h rainfall-induced erosion; (c) and (f) mean profile depth on the surface as a function of rainfall-induced eroded time. (a), (b), and (c) are for 0.5 M Ca MICP-treated sample, whereas (d), (e), and (f) are for 10% cement-treated sample.
