Material parameters used in the numerical simulations.

Material	/(MPa)	/(kN/m^3)	/(kPa)	/(°)			/(m)
Embankment fill	20.0	19.0	16.8	24.6	0.30	0.50	5.0
Silty clay	5.2	17.2	14.2	18.3	0.33	0.65	3.5
Silty soil	7.6	17.8	7.6	19.7	0.33	0.65	6.0
Gravelly sand	30.0	20.1	0	28.6	0.30	0.65	4.0
Clay	22.1	18.3	15.7	21.0	0.30	0.80	6.5

Note: is elastic modulus; is unit weight; is Poisson’s ratio; is cohesive strength; is friction angle; is height of embankment fill; and is thickness of soil layers.
