    Coulomb Earth Pressure

    Can coulomb active earth pressure be greater than 1.0? For the case: wall backslope from vertical = 45degree wall backslope from horizontal = 45 degrees retained soil backslope = 16 degrees friction angle = 30 friction between wall and backfill = 14 degrees I calculate Ka= 1.396
