The stratigraphy in a site from top to bottom are (1) 4.5 m thick sand; (2) 4.5 m thick clay; (3) impermeable shale. The water table is at a depth of 2 m below ground. The sand above the water table has a void ratio of 0.52 and a saturation degree of 37%. The clay has a moisture content of 42%. The specific gravity of both the sand and clay is 2.65. If constructing a foundation whose bottom is at a depth of 3m, resulting in the extra stress at the top and the bottom of the clay layer is 100 kPa and 40 kPa, respectively. According to the consolidation test, the void ratio of the clay corresponding to 50, 100 and 200 kPa are 1.02, 0.922 and 0.828, respectively. The settlement of the clay layer will be_____________(mm). (One-dimensional settlement is applicable. The density of water is 1000 kg/m3)

(a)
At a reclamation site, a 6-m thick sand layer overlies a 5.8-m
thick clay layer, which is underlain by impermeable rock stratum.
The water level is initially 2.5 m above the ground surface. The
saturated unit weights of sand and clay are 19 kN/m3 and 17 kN/m3,
respectively. A 5-m thick layer of fill will be placed on the
original ground surface, and the unit weights of fill are 19 kN/m3
and 20 kN/m3 above and below water table,...

A clay layer in field is 3-m thick and is sandwiched between two
sand layers (drained from top and bottom). The saturated stratum of
clay is under a surcharge loading and underwent 90% primary
consolidation in 75 days. The time required in minutes for a 30 mm
thick undisturbed clay sample obtained from the field to undergo
90% consolidation in laboratory is most nearly equal to

Problem No. 1 The soil profile at a site consists of a
top 4 m layer of dense sand followed by 2 m of clay, which is
underlain by a stiff stratum. The water table is at 2 m below the
ground level. The follow- ing data was obtained from a
consolidation test on an undisturbed sample obtained from the
middle of the clay layer: water content 36%, specific gravity of
the clay grains = 2.72, compression index = 0.72,...

The soil profile at a site consists of a clay layer 10 m thick,
sandwich between two sand layers. The top sand layer has a density
of 1.9 Mg/m3 and is 5 m thick. Below this layer is a 10 m thick
clay layer with a saturated density of 1.8 Mg/m3 and a saturated
water content 42%. The deeper sand layer has a saturated density of
1.9 Mg/m3 and extend to the depth investigated at the site. The
water table...

Why do ventricles need to squeeze from the bottom of the muscle
to the top of the muscle?
A. To ensure that ALL of the blood makes it from the ventricles
into the pulmonary artery and aorta
