�l U TR BLOCK, INC. DESIGN DATA TARGET DESIGN VALUES (Factors of Safety - Static / Seismic) Minimum Factor of Safety for the sliding along the base Minimum Factor of Safety for overturning about the toe Minimum Factor of Safety for bearing (foundation shear failure) MINIMUM DESIGN REQUIREMENTS Minimum embedment depth INPUT DATA Geometry Wall Geometry Design Height, top of leveling pad to finished grade at top of wall Embedment, measured from top of leveling pad to finished grade Leveling Pad Depth Face Batter, measured from vertical Slope Geometry Slope Angle, measured from horizontal Slope toe offset, measured from back of the face unit Slope Length, measured from back of wall facing NOTE: If the slope toe is offset or the slope breaks within three times the wall height, a Coulomb Trial Wedge method of analysis is used. Surcharge Loading Live Load, assumed transient loading (e.g. traffic) Live Load Offset, measured from back face of wall Live Load Width, assumed strip loading Dead Load, assumed permanent loading (e.g. buildings) Dead Load Offset, measured from back face of wall Dead Load Width, assumed strip loading Soil Parameters Retained Zone Angle of Internal Friction Cohesion Moist Unit Weight Foundation Angle of Internal Friction Cohesion Moist Unit Weight FSsl =1.50 /1.125 FSot =1.50 /1.125 FSbr =2.00 /1.500 Min_emb =1.00 ft H =7.50 ft emb =1.00 ft LP Thickeness =0.50 ft i =0.00 deg R =0.00 deg STL_offset =0.00 ft SL_Length =0.00 ft ILL = 150.00 psf LL_offset =1.00 ft LL_width = 8.50 ft DL=0.00psf DL_offset =0.00 ft DL_width = 0.00 ft cp = 34.00 deg coh =0.00 psf gamma=130.00 pcf cp = 36.00 deg coh =0.00 psf gamma=130.00 pcf UltraWall 4.0.16287.0 Page 4
