Unformatted text preview: sum the layer contributions n n Q s = IQ sI = IfslA s ! i=1 i=1 o End Bearing: use the design method appropriate for the bearing layer weak layers within BB above toe and 35B below toe will affect bearing capacity for sands the critical depth limitation applies starting at top of bearing layer (D, measured from top of bearing layer not the soil surface) o Drained V5. Undrained: do not mix drainage behavior in same analysis, all layers are drained or all layers are undrained (use effective stress analysis for sands in either case) use drained analyses for unsaturated soils a Example Side Shear Profiles: I Q 1 (for Clay at toe)...
