ABSTRACT
Figure 4 shows the typical CPT profiles obtained in the T2 Zone. As can be noted that the six-sublayer sequence in the Sungshan Formation is clearly identifiable. The various soil sublayers can better be identified in the porewater pressure profile than tip resistance or local friction. In short, Sublayers I, III and V consist primarily of silty sands and Sublayers II, IV and VI consist primarily of silty clays. The sandy sublayers, i.e., Sublayers I, III and V, thin out toward the east and the north of the basin and become unidentifiable in the K1 Zone as can be noted in Figures 1 and 2. TK2 Zone is a transition between T2 and K1 Zones.
