Otherwise,eq.38 is utilized) Inclination of intemal slip plane, kV=6 L00° (see Fig.28 in DEMO 82). Ka(external stability)=0.3073 (if batter is less than 101,Ka is calculated from eq. 16. Otherwise,eq. 17 is utilized) BEARING CAPACITY Bearing capacity coefficients(calculated by MSEW): Ne=35.49 N y=30.21 SEISMICITY Maximum ground acceleration coefficient,A=0,300 Design acceleration coefficient in Internal Stability: Kh=Am=0.345 Design acceleration coefficient in External Stability: Kh d=0.165 => Kh=Am=0.212 (Kh in External Stability is based on allowable displacement, d=25 mm.using AASHTO 2002 equation) Kae(Kh>0)=0.4130 Kae(Kh=0) =0.2705 A Kae=0.1424 Seismic soil-geogrid friction coefficient,F*is 80.0%of its specified static value.
