Civil Engineering 4) a) The soil reinforced retaining wall shown in figure Q4 is founded on sand having the properties shown in the figure. Allowing for an unplanned excavation of 10% of the unsupported wall height, calculate the factor of safety against sliding. Assume the water table is located at great depth and the coefficient of friction between the wall and the supporting soil is 0.55. Surcharge q = 10 kPa Reinforced earth retaining wall y = 20 kN/m? 5 m 0.9 m Sand c' = 0 kPa 4, = 35 degrees Ysoil = 20 kN/m 4.0 m Figure Q4 |
