<br /> SOIL DATA
<br /> REINFORCED SOIL
<br /> Unit weight, y 125.0 lb/ft I
<br /> Design value of internal angle of friction, 32.00
<br /> RETAINED SOIL
<br /> Unit weight, y 125.0 lb/ft 3
<br /> Design value of internal angle of friction, 32.00
<br /> FOUNDATION SOIL(Considered as an equivalent uniform soil)
<br /> Equivalent unit weight, y e4u;v 125.0 Ib/ft I
<br /> Equivalent internal angle of friction, +equiv 32.00
<br /> Equivalent cohesion, c equly 0.0 lb/ft 2
<br /> Water table does not affect bearing capacity
<br /> LATERAL EARTH PRESSURE COEFFICIENTS
<br /> Ka(internal stability)=0.3073 (if batter is less than 10°,Ka is calculated from eq. 15, Otherwise,eq.38 is utilized)
<br /> Inclination of internal slip plane, tp=61.00' (see Fig.28 in DEMO 82).
<br /> Ka(external stability)=0.3073 (if batter is less than 10o,Ka is calculated from eq. 16. Otherwise,eq. 17 is utilized)
<br /> BEARING CAPACITY
<br /> Bearing capacity coefficients(calculated by MSEW): Nc=35.49 N y=30.21
<br /> SEISMICITY
<br /> Maximum ground acceleration coefficient,A=0.300
<br /> Design acceleration coefficient in Internal Stability: Kh=Am=0.345
<br /> Design acceleration coefficient in External Stability: Kh d=0.165 => Kh=Am=0.212
<br /> (Kh in External Stability is based on allowable displacement, d=25 mm.using AASHTO 2002 equation)
<br /> Kae(Kh>0)=0.4130 Kae(Kh=0) =0.2705 A Kae=0.1424
<br /> Seismic soil-geogrid friction coefficient,F*is 80.0%of its specified static value.
