<br />I-AI'F.,RAL EARTH PRESSURE COEFFICIENTS
<br />Ka (interrial stability) = 0.2827 (if batter is less than 10°, Ka is calculated from eq. 15. Otherwise, eq. 38 is utilized)
<br />Inclination of internal slip plane, W =,,. 62.00' (see Fig. 28 in DEMO 82).
<br />Ka (external stability) = 0.3073 (if batter is less than 10°, 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 = 0.330
<br />Design acceleration coefficient in Internal Stability: Kh = Am = 0.370
<br />Design acceleration coefficient in External Stability: Kh_d = 0.186 => Kh -Am— 0.235
<br />(Kh in External Stability is based on allowable displacement, d = 25 mm. using AASHTO 2002 equation)
<br />Kae ( Kh > 0 ) = 0.4322 Kae(Kh=0) —0.2705 A Kae=0.1617
<br />Seismic soil-geogrid friction coefficient, F* is 80.0% of its specified static value.
