a. Total stress, pore pressure, and effective stress at point C. b. The proposed structure with the footing size of B=6 ft, L=10 ft. has to transfer the design load of 150 Kips. What will be the vertical stress increase at point A in Ib/ft, located at the corner of footing and depth of 4 ft. due to loading?

You have been given the results of a recent geotechnical exploration for a local project. The groundwater table at the time of exploration was 4 ft from the existing ground surface.
This is also the interface between the SC and MH soil layers. Figure provides the soil profile at the time of geotechnical exploration. From the provided information, calculate the
followings:
a. Total stress, pore pressure, and effective stress at point C.
b. The proposed structure with the footing size of B=6 ft, L=10 ft, has to transfer the design load of 150 Kips. What will be the vertical stress increase at point A in Ib/ft2, located at
the corner of footing and depth of 4 ft, due to loading?
