1) Due to the construction of a building, 150 kPa vertical stress increment takes place in a clay layer. The thickness of clay layer is 8m and there are a very thin sand layer above and a thick sand layer below it. If the final settlement is 0.08m, calculate the followings:
a) Required time in terms of month for 0.04m consolidation settlement
b) Amount of settlement in terms of meter, after 4 months of construction
c) During the construction, a machine is intended to be placed in to the building. However, the machine is sensitive to the settlement and amount of the settlement should not exceed 0.02m after placing this machine. Calculate the required time to satisfy the prerequisite in terms of months.
d) k value of the clay layer
mv = 1*10-4, cv = 0.4 m/month
