A layer of soft, normally consolidated clay is 15 m thick and lies under a newly constructed building. The overburden pressure of the sand overlying the clay layer is 500 kN/m2 and the new construction increases it by 180 kN/m2. If the compression index is 0.25 and the recompression index is 0.015, compute the settlement of the building. The water content of the clay is 30%, the specific gravity of the soil grains is 2.7, and the clay is fully...

A Normally Consolidated 10 Ft. clay layer is surcharged, which causes a decrease in thickness. The coefficient of consolidation is 0.16 ft^2/day and the time factor is 1.2 for U=50%. The clay layer is confined between 2 layers of dense sand. The time (days) required for 50% consolidation is most nearly? This is a question from a practice FE exam. The reference book and the solution to this leaves out some information. The equation is Tv=Cv(t)/Hdr^2) The solution has Hdr=5...

A 20 m thick saturated clay layer is normally consolidated. At mid-depth in this layer, the void ratio (e) is 1.110, the coefficient of compressibility (av) is 5.74 x103 cm2=N. Recall that w = 9.81 kN/m3. a) Assuming that a 122 cm lowering of the ground water table (GWT) occurs in the soil overlying the clay layer, what settlement will occur in the soil overlying the clay layer because of the ultimate primary consolidation of the clay layer? Express your...
