QI/ A sandstone rock specimen has que= 50 MN/m² and Ø= 35º. Find c. Q2/ A sandstone bed with RQD= 70% and y = 26.0 kN/m³ lies beneath 1.5 m of overburden soil. A 2.0 m x 2.0 m square foundation is to be placed on top of the sandstone rock (i.e., at a 1.5 depth below the ground level) to carry a column load. The unit weight of the soil is 18.0 kN/m. Assuming the rock strength parameters from Problem Ql, determine the maximum load that can be allowed on the foundation with the safety factor FS = 3. The compressive strength fc of concrete is 30.0 MN/m².
