Scenario The wall footing at right is to be constructed to carry an inclined load at 85 degrees with the horizontal, as shown. Assume that there is impenetrable bedrock below the Sample point shown in the figure. 1) Calculate the expected primary settlement of the soil at the Sample point. Also, determine the time it will take for 60% of the expected primary settlement to occur. 2) Determine the factor of safety against bearing failure of the soil for the wall footing if qult of the soil is 160 kN/m2.
Question #2
Separate triaxial compression tests are performed on identical soil samples. The soil is saturated mixed soil. At failure, the respective minor and major principal stresses values are 10 kPa and 30 kPa for sample one, and 40 kPa and 70 KPa for sample two. From these data, determine the value for ∅ and the cohesion intercept C on the Mohr’s circle shear strength coordinate. Show all hand calculations and diagrams.
Question 8 A gulf coast formation at 7,500 ft is drilled using 10.5 lb/gal mud.
