From: Effects of rock content and spatial distribution on the stability of soil rock mixture embankments
Sensitivity Analysis of ESRD Equation Parameters: (a) Parameter A1;(b) Parameter t1; (c) Parameter y0.
The parameters A1 and y0 were more sensitive to changes in Rc, while t1 was more sensitive to changes in the spatial distribution of rock blocks. In embankment fill engineering, increasing the Rc (Rc ≤ 60%) significantly enhanced embankment stability. When Rc > 60%, further increasing the Rc had less effect on improving stability. For the same Rc, placing more rock blocks at the slope crest could enhance embankment stability.
