CE Board HGE Problem 54 (Hydraulics and Geotechnical Engineering)

(CE April 2024) Evaluate the plastic settlement, in meters,on a layer of plastic clay due to an increase of pressure caused by loads above it.

Under the following conditions:

Initial intergranular pressure = 180 kPa
Increase in intergranular  pressure = 120 kPa
Thickness of clay layer = 8 m
Coefficient of consolidation = 0.315
Void Ratio of the clay = 1.132
