Laboratory Experiment and Numerical Analysis on the Precursory Hydraulic Process of Rainfall-Induced Slope Failure

Figure 11

Evolutions of pore-water pressure leading to the five consecutive failures at the nodes corresponding to slip surface locations. On a color spectrum from blue to yellow, the darkest blue line indicates a node at the lowest elevation, whereas the brightest yellow line indicates a node at the highest elevation. (a) At nodes corresponding to the 1st slip surface. (b) At nodes corresponding to the 2nd slip surface. (c) At nodes corresponding to the 3rd slip surface. (d) At nodes corresponding to the 4th slip surface. (e) At nodes corresponding to the 5th slip surface.
