4.A layer of saturated clay is 10 m thick, the lower boundary being impermeable;an embankment is to be constructed above the clay. Determine the time requiredfor 90% consolidation of the clay layer. If 300 mm diameter sand drains at 4 mcentres in a square pattern were installed in the clay, in what time would the sameoverall degree of consolidation be reached? The coefficients of consolidation inthe vertical and horizontal directions, respectively, are 9.6 and 14.0 m^2/year.
The water table at a site is at 5 m below the ground level, and it is required to excavate to this level. The soil profile consists of a thick bed of sand where the unit weight is m = 17.0 kN/m3 above the water table and sat = 20.0 kN/m3 below the water table. The friction angle of the sand is 37. The wall of the excavation will be supported by cantilever sheet piles. How deep would you drive the sheet piles? Use the simplified analysis (Figure 15.37) with a factor of safety of 1.5 on the passive resistance. Determine the maximum bending moment in the sheet pile and the required section modulus for the sheet pile section (given an allowable stress of 190 MN/m2).
