For the bridge abutment shown below, find (a) The horizontal soil pressure EH applied along the depth of the abutment. (b) The horizontal earth surcharge pressure ES applied along the depth of the abutment. (c) The vertical soil pressure EV on the abutment footing. Assume that soil density remains approximately constant through the depth of the abutment and the abutment does not deflect or move sufficiently to reach an active condition. Use soil den- sity Ysoil = 0.11 k/ft. The fill material consists of a well-graded gravel-sand mix. The soil friction angle of = 30. 0.65 k/ft? 10 +3-04 -19-0- -7'-0-
