Question IV (30%):
A 22 m thick normally consolidated clay layer has a
load of 150 kPa applied to it over a large areal extent. The clay layer is located below a
3.5 m thick granular fill (p= 1.8 Mg/m³). A dense sandy gravel is found below the clay.
The groundwater table is located at the top of the clay layer, and the submerged density
of the clay soil is 0.95 Mg/m³. Consolidation tests performed on 2.20 cm thick doubly
drained samples indicate the time for 50% consolidation completed as t50 = 10.5 min for
a load increment close to that of the loaded clay layer. Compute the effective stress in
the clay layer at a depth of 16 m below the ground surface 3.5 years after the
application of the load.
13-3. Use the moment-distribution method to determine
the moment at each joint of the symmetric bridge frame.
Supports at F and E are fixed and B and C are fixed
connected. Use Table 13-2. The modulus of elasticity is
constant and the members are each 0.25 m thick. The
haunches are parabolic.
