1. A wide fill will apply a uniform pressure of 100 kN/m? to the surface of a soil profile consisting of 3 m of weathered clay (y = e, = 1.2, C. = 0.5, o,/o, = 5, C,IC. 0.2) over 7 m of marine clay (y C. = 1.5, o,lo, = 1.8, C,/Cc = 0.1) over 5 m of lacustrine clay (y = = 1.7, C. = 1.2, o,lo = 1.0, Ca/C. = 0.05) over granular till. The water table is 3 m below ground surface. Compute settlement resulting from primary consolidation of: (a) weathered clay and (b) marine clay. Com- pute settlement resulting from consolidation of the lacustrine clay after 50 years assuming that primary consolidation is com- pleted in 14 years. 17.6 kN/m', %3| = 16.0 kN/m³, e, = 1.8, = 16.3 kN/m', e. 1.2, o,lovo %3D Ans. 7 cm; 53 cm; 68 cm.

Transcribed Image Text:1. A wide fill will apply a uniform pressure of 100 kN/m2
to the surface of a soil profile consisting of 3 m of weathered
clay (y = e, = 1.2, C. = 0.5, o,/o, = 5, C,IC.
0.2) over 7 m of marine clay (y
C. = 1.5, o,lo, = 1.8, C,/Cc = 0.1) over 5 m of lacustrine
clay (y = 16.3 kN/m2, e, = 1.7, C. = 1.2, o,lo, = 1.0,
Ca/C. = 0.05) over granular till. The water table is 3 m below
ground surface. Compute settlement resulting from primary
consolidation of: (a) weathered clay and (b) marine clay. Com-

clay after 50 years assuming that primary consolidation is com-
pleted in 14 years.
