Question

A line load of 262kN/m acts at a distance d= 4.6 m from the front face of the retaining wall having the following dimensions in metres (height=2.0, a=0.48,5=2.3,x=0.5.y=0.4, and z=0.7. Calculate the additional vertical stress (kpa) at the top left corner of the heel due to the line load. (2 d.). a S h Toe Heel

1) Show the top left corner of the heel and the distance to the line load.

2) Calculate the additional vertical stress (kpa) at the top left corner of the heel due to the line load. Use the following equation z - depth and x, perpendicular distance to line load.
