A 2 m thick clay is singly drained. A structure founded on the surface applied an average stress increase of 50 kPa to this clay layer. A piezometer is installed at the mid-depth of the clay layer. A. What would you expect the initial excess pore pressure reading on the piezometer to be immediately after application of load? B. The piezometer recorded a pore pressure of 25 kPa, 1-yr after the application of the stress. What would you expect it to read 2 years later? What is the coefficient of consolidation of this clay in cm²/s? C.
