Figure 6. Multiple reconsolidation-consolidation cycles on a sample from Section 149-897D-3R-2, 73-103 cm. The yield stresses (
c') are very poorly defined on
v-v' plots, but are more clearly shown by other relationships. The second (normal) reconsolidation produced yield stresses (both
v' and
h') identical to the stress state at the end of the first reconsolidation. The third
(overconsolidated) reload produced yield stresses significantly less than those at the previous consolidation state.
