A 5 m thick doubly drained normally consolidated clay layer at a site has e, = 0.95, C, = 0.54, and c, = 4.0 m/ year. The effective overburden pressure at the middle of the clay layer is 70.0 kN/m². Some proposed construction work is expected to impose a 60.0 kN/m² load at the ground level.

Question

Noting that the expected primary consolidation settlement
is high, it is proposed to apply a surcharge over
a period of one year. What should the magnitude of
this temporary surcharge be so there will be no postconstruction
consolidation settlement?
