1. Please find the possible solutions for this question! As shown in figure given below, a spread footing is planned to support a column. The load on the column, including the weight of the foundation, is 2000 kN. The foundation is also subjected to a horizontal load that causes an overturning moment of 200 kNxm. The foundation is in silty sand. Subsurface exploration and laboratory testing found that the soil's effective cohesion is 25 kN/m? and the effective friction angle is 22. The groundwater table is 1.5m below the ground surface. The bulk unit weight above the groundwater table is 16.5 kN/m; the saturated unit weight below the groundwater table is 17.5 kN/m'. The foundation embedment is 0.6m, and dimension is B x B = 1.2m x 1.2m. Calculate the factor of safety for the bearing capacity using Terzaghi approach! Please discuss the details of your findings!

Transcribed Image Text:1. Please find the possible solutions for this question! As shown in figure given below, a spread
footing is planned to support a column. The load on the column, including the weight of the
foundation, is 2000 kN. The foundation is also subjected to a horizontal load that causes an
overturning moment of 200 kNxm. The foundation is in silty sand. Subsurface exploration and
laboratory testing found that the soil's effective cohesion is 25 kN/m? and the effective friction
angle is 22°. The groundwater table is 1.5m below the ground surface. The bulk unit weight
above the groundwater table is 16.5 kN/m³; the saturated unit weight below the groundwater
table is 17.5 kN/m'. The foundation embedment is 0.6m, and dimension is B x B = 1.2m x
1.2m. Calculate the factor of safety for the bearing capacity using Terzaghi approach! Please
discuss the details of your findings!
