The time factor T_v in the consolidation equation T_v = C_v×t/H² is dimensionless, and H represents:
Choose the correct answer
The total thickness of the clay layer
The length of the drainage path (= H/2 for double drainage)
The settlement at time t
The initial void ratio
Correct Answer
B. The length of the drainage path (= H/2 for double drainage)

H in the time factor is the maximum drainage path length. For double-drainage (permeable layers above and below), H = half the total layer thickness. For single drainage, H = full layer thickness.
