Abstract:
The authors have conducted a noteworthy numerical study investigating the influence factors for rainfall-induced shallow slope
failure. Specifically, the authors evaluated the influence of soil
saturated hydraulic conductivity, slope angle, and antecedent
rainfall on the stability of a shallow slope. The rainfall intensityduration (ID) thresholds were established from the numerical
results, and they were comparable to those based on the historical
slope failure data in the existing literature. In this discussion paper, the discussers would like to comment on the Undrained function selected for modeling the mechanical behavior of soil layers
in the finite-element (FE) analyses in the discussed paper (as indicated in Table 3 in the original paper).
